Trying to manage the weeds in your vineyard? John Roncoroni, Weed Science Farm Advisor Emeritus with the University of California Cooperative Extension, Agriculture and Natural Resources covers control practices including biological, mechanical, cultural, chemical, and perhaps in the future, electrocution. Although weeds rarely compete with vines, they can host insect and vertebrate pests and get in the way of pruning crews, increasing labor costs. Listen in for John's number one tip to better manage weeds in your vineyard.

He is Weed Science Farm advisor emeritus with UC Cooperative Extension, UC Agriculture Natural Resources, and we're going to talk about cultural control of weeds in vineyards today. Thanks for being on the podcast, John.   John Roncoroni  0:13  Now you bet, Creg, thank you for having me.   Craig Macmillan  0:16  We met with we'll start with kind of a basic foundation, what would you say is the definition of cultural weed control? Maybe How does it differ from other forms of weed management?   John Roncoroni  0:25  cultural weed control as part of an integrated pest management program, you know, we have basically cultural mechanical, sometimes they're put together sometimes they're split, we have biological, which is much more important, I think, in insects than it is in weeds. Now, we talk about biological control of weeds just a little bit to show how it fits in with all this too, is that you know, when you see that rust growing on a malba, or cheese weed plant in California, people say, Well, maybe that can control and you can see sometimes it really weakens the weeds. But the one reason that doesn't work here very well as it does in other places is the same reason why we can grow such great grapes and make great wines in California is because it doesn't rain in the summertime, if it rained in the summertime, like it does. In many other areas, that moisture level would stay up and we probably have a better chance of controlling Malba. We do use biological control of weeds in more landscape like range land type at large areas, but really on any kind of agricultural situation where we're looking at control in one spot, it really doesn't work that well. Even with star thistle we be talking about people wanting to put our application of of weevils for start thistle. Well, they're out there, and they're on a larger scale. So that's biological, much more important in entomology than in Weed Science, a chemical control, obviously, the use of chemicals, either conventional or organic chemicals or control. And then we have mechemical or cultural you know, cultural weed control to me is using the utilizing the plants that are there or sheep in areas of the San Joaquin Valley that used to use ducks or geese to pull out Johnson grass rhizomes, yeah, we're utilizing sheep quite a bit more. Now. Of course, mechanical we're looking at when you look at something like a mower, right, a mower is mechanical and cultural because when you mow, you're leaving some plants. So you're mechanically mowing them down. But culturally, you're leaving plant where something like French flower, maybe a blade or or you know, one of the the weed knives are all the different moving wheels, maybe more considered mechanical.   Craig Macmillan  2:30  Let's talk about mechanical a little bit. There was a book I don't know if it's still in print. And it was a SARE book. And it was called steel in the field. And the author's thesis or premise or idea was if you drive around farm country, no matter what the crop is, there's always a graveyard of old implements, just parked just parked there, you know exactly what I'm talking about.   John Roncoroni  2:51  Oh, god. Yeah.   Craig Macmillan  2:54  And his his point was, all of those things were technologies that someone had come up with. And then the individual farmer, probably then made modifications to those for their site for their crop for their soil, then the herbicide era came on. And that wisdom was lost, basically. And the argument was, hey, maybe we can bring that that idea back. And I mean, this goes back to like the 80s, early 90s. It's happening, it's happened. What are some of your favorite technologies in terms of cultivation, mechanical weed control, and some of the limitations, some of the plants that works well with other situations where it doesn't? What's your experience been?   John Roncoroni  3:39  I love talking about that, Creg, is it you know, talking about using mechanical control, and then and then going into chemicals, and now going back, it's almost like I talked to people about chemical control itself. When I started, Roundup wasn't glyphosate was a new thing. And we used it very judiciously. And I tell people, it's almost like, I learned to drive with a stick shift. I had to learn all these other things. Well, after that people learned to drive automatics. Right, because they knew one way to do it. Well, now that we're back to using stick shift, it's a whole lot easier for me, because I remember now people have to read or write. It's, it's the same thing with the mechanical. And when I started a Davis, you know, in the early 80s, we probably first came to work in vineyards in Napa, close to Davis, about 85, 86. And at that point, there was a lot less drip irrigation, a lot more dry farming, and a lot more French plowed. One of the reasons was we didn't have drip irrigation. I mean, we all want deep roots, but you're going to have more shallow roots with drip irrigation. And that was one of the reasons we moved to chemicals away from this big pasture. We always had a blade, right something like to drop a name a Clemens blade, which we all know what that is. It just cuts. You know, one of the problems with that is if the soil is too moist, then it's going to cut and go right back. And there's been a lot of innovation. My colleague Marcela Moretti, a But Oregon State's done a lot of testing with different kinds of machines. You know, one of the things about mechanical or even like mowers is that so few growers have mowers?   Craig Macmillan  5:11  When you say mower? You mean an in row mower?   John Roncoroni  5:13  Yeah, I mean inrow mower. All right. And I'm sorry, I when I talk about weeds in vineyards, because I tell people I've made my whole career out of about three   Craig Macmillan  5:21  Three to six inches.   John Roncoroni  5:24  I have about a foot and a half. Right? Sometimes I'm up to four feet, right. So that's where my whole career is right there. And that we talk about when we talked about what we're doing in the middle is with cover cropping. That's a whole other podcast and probably, I mean, I've done cover crop work over the years with some large IPM grants. I did quite Elmore and some other things. Zalem and Jim McDonald Yeah, no, I'm talking about just under vine we're thinking. Yeah.   Craig Macmillan  5:53  All right we're under vine.   John Roncoroni  5:54  Talk about being a very specific expert - four feet. At the most.   Craig Macmillan  6:01  I got it. I get it.   John Roncoroni  6:02  You know, very few growers are using mowers we have the big bladed mowers and also we'll have a straight trimmer. I was trying to do some string trimmer work, but just using a little weed eater. My old friend, Mike Anderson, who was the superintendent or basically ran the oppo research station said that I could use a string trimmer in one of their vineyards over his dead body. And I was like, you don't want any girdling in those vines. So I know, there's been a lot of apprehension. There are some other kinds of mowers very, very, very few growers have mowers, from what I've just done some surveys, I've done one because you have to go back over and over and over, right? And then everything has been weighed against, well, we can just spray mowers or one, you know, there's several different and I can't remember all the trade names. But you know, there's some of the basic technology. Yes, there's some that do some stirring of the soils, you know, with blades that are perpendicular to the soil, right. So they're, they're stirring it, there's what we used to call and when I worked in bean weed control, Lilla stuns, which are wheels that turn sort of at a 45 degree angle to stir the soil. There's, you know, power driven machines, there's just ones that ride along and there's blades, there's, you know, there are so many, and it really depends on the kind of soil you have, you know, our rocky is sometimes the place where we put grapes are not a place where you could put tomatoes, right in times, shallow soil, hillsides, kind of cultivation, can you can you do cultivation? Can you do light cultivation without getting you know, soil movement? Can you even do it? Is it allowed by, you know, some rules about land use in those areas. So, there's a lot of things that go into mechanical and again, from my perspective, the weeds you have.   Craig Macmillan  7:54  I like this point here, because I think put to put things into kind of a general sense to guide things. We have blades that basically cut just below the surface. So that's cutting off the top of the plant from the bottom of it for certain kinds of plants that will kill it or control it. Then we have things like a French plow, which is a burying it's a true plow. Yeah, it's flipping soil, picking it up and flip flopping it over. Then we have the sturer. So you mentioned that little stun the central lines and other example, sun flowers. That's what they do. Yeah. Yeah. Things like that. My missing one.   John Roncoroni  8:26  mowers.   Craig Macmillan  8:27  mowers, okay. Yeah.   John Roncoroni  8:29  So that, you know, then there are a lot of variations on those combinations. It just amazing for me, and I follow a few of the manufacturers and get to see like on Twitter X, whatever, to see the videos that they're posting on LinkedIn. You know, it's just amazing to me what they're doing and the innovation that's going into those. One of the things that my again my colleague Marcel HomeReady, up at Dr. Moretti up at Oregon State talks about making sure your tractor is big enough for some of these, you know, hydraulic using, right, but one of the things we always used to talk about was, you know, the use of gas well, I know there's a lot more use and we're moving more into electric tractors, and those sorts of things. But when it comes to mechanical, really doing a good job of mechanical weed control with those some of those, you're going to have to have electric or gas you're going to have to have a big tractor. They're not going to be like a you know, a little ATV with a nifty 50 sprayer spraying herbicides right you're gonna need some hefty equipment in a lot of them not always.   Craig Macmillan  9:33  Let's start with weed knife. That's a very popular technology you see it oh yeah all over the place. What are the kinds of weeds that that's good for controlling and under what conditions it doesn't work well and under what kind of conditions does it not work well?   John Roncoroni  9:47  And I don't know the areas and passive as well as I know Napa I was brought a while but I would tell the growers you know, using a weed knife in Carneros you have about four days from when the soil goes from being too wet to being too dry. I have heavy clay soils, it holds moisture and it just. Yeah, exactly. And I'm sure there are areas like that, you know, and it can't, you can successfully cultivate down there, but it's tough, you need the timing, it's so important. If you're going to wet that soil just goes right back with that blade, right you cut through and the roots are able to tell back in, you know, if it's too dry, it's really going to be a rough ride. Because you're not going to go too deep, it's going to work well on some smaller annual weeds, which, you know, a lot of our weeds are, you know, some of the grasses with their net have a root ball sometimes are harder than just a small annual broadleaf plant, you know, you're going to have some problems, especially with something like malware, cheese weed that that grow very large. And depending on when you doing it something like cheese weed is and rye grass and Fillory, while I mentioned them are the first weeds to germinate in the fall. So by the time you get in a little bit later, they may be too big to really do a very good job on.   Craig Macmillan  10:59  Are their soils where we die for it's particularly well?   John Roncoroni  11:03  I would say you know, in less than heavy clay soil and not complete sand, a sandy loam soil, I think that holds some moisture, you know, it was able to get in anything, I think it's not a complete stand or a real heavy clay, they do a nice job, but the weeds can't be too big. And again, it's that timing and you know, with vineyards, it seems to think everything happens at once right time when you may be in having to do some sort of insect spray or mold spray, the same time you should be out there cultivating so just and it takes a while to do a good cultivation job.   Craig Macmillan  11:35  The speed that you're rolling is really important. You want to be slower ride faster.   John Roncoroni  11:40  Well, and Dr. Moretti has done this work there is an optimum speed. If you go too slow, then you really don't do a good job of cutting. If you go too fast, you miss some. And maybe this is where some of the electric AI technology can help. You don't want to cut the vines. Right, so you have this pull away, that keeps the weeds, the weeds will go right next to the vines, which you know can be a problem. We'll be talking about other situations with little vertebrate pets.   Craig Macmillan  12:06  I'm kind of getting astray here a little bit, but I No, no, but I think this is an important question. So choosing what I do and how I do it, we go back to the other technologies, Why care about weeds? Right? Why care about you know, I had I had a vineyard once that had been an oak field. And it was direct planted own rooted sprinkler system that was planted in 1976 I got the vineyard 1993 out of heavy clay soil, and I would irrigate with sprinklers twice a summer, and that oak grass would grow up into the fruit zone up into the canopy. But it would dry out. And it completely choked out everything else I had, I had no other real issues. And we would mow the middles. And I remember people going oh my god, you got all this issue, you need decent herbicide, you think grass out of the middle because the grass is gonna. And like these vines were super vigorous. They were tons of crop. I mean, I had to crop thinner. And so I started asking myself, well, how much competition? Is this really doing? Are there particular weeds that we should see? And you're like, wow, that's gonna be a competitor for water, nutrients and others where we go, No, I don't really want it there. But I'm probably not going to dig my vines.   John Roncoroni  13:13  So Craig, this is the eternal question when it comes to this. And it really depends on where you grow your grapes, right? If your goal is to get 25 tons of grapes, if you're somewhere near Bakersfield won't offend anybody, but they're looking more for tonnage. Right. And I've gotten a lot of flack for using our premium grape situations, we're not always looking for maximum tonnage. Right. And I don't know that the problem with weeds and if you hear me speak about weeds, I rarely have ever talked about direct competition between weeds and grape vines. Now, there are some exceptions, you know, when we were looking at that balance between irrigation and getting the deficit, irrigation, right, getting those maximum flavors into those grapes. So we may be right and a little low with our water in August or September, near the end. And we see that especially, I don't know so much about about I know, part of the areas where we are with the vineyard team there that they gave, we can get these howling north winds, right? Right. And you can in a very short time, you can turn some very great, expensive grapes into really great expensive raisins, right, getting that water in at that time of year. So having any kind of like flu Velen, which is really just covers the whole area of Napa and Sonoma. I know it's moving around some other areas. But you know, people say well, how much water does it use? And my old friend Rhonda Smith used always asked me well, how much water is it used? I go, we don't have crop coefficients for all the crops. It's hard to know which you know which weeds grow, how much water they use. And then the other thing too, is that if we're looking for consistency in a vineyard, and only half the vineyard is covered with that weeds where we're gonna put two too much water in one area and not enough in the other. Isn't that different? So it's competition for that sort of thing. And of course, young vines, right when we have young vines with big weeds and that that oak grass that you had, if you had young vines, you probably wouldn't have to be worried about being a grape grower very long, right?   Craig Macmillan  15:17  You have seen that young, really healthy barley cover crop?   John Roncoroni  15:21  Oh, yeah, it's it's tough for first three years. But like talking about establishments, it's really important, no matter what you do to keep the grapes sort of weed, not weed free, but really keeping the competition down. And then late in the summertime, but the rest of the time. It's other things that I've talked about these, it's one of those things where you ask people, you know, raise their hand if they have this problem. It's 50%. Yes. 50%. No. And that's voles. And I tell people, I thought that when I was in Napa, I think 30% of the growers do weed control strictly for vole protection. Because those nasty little marmots can they can girdle a grape. And I know one vineyard and Carneros they couldn't get in and do some work. Someone told me that one year they lost one in five vines. Wow. And they're not coming back. Right? That's, that's bad. Yeah. So you know, it can be a problem. We found this when we were working with mow and blow technology years ago, looking at cutting cover crop and throwing it on the vine. The Weed control was fantastic. But in my whole time, working in vines from 1985. And, you know, until today, I've never been in a vineyard, except in this trial, where I saw voles running between the rose in the middle of the day. Right, they were just happy there was so many they kind of had to get out just to get a breath of fresh air, they use those tunnels, you know, just runway so that they were protected from that, you know, the birds of prey, which you know, can help. And I people always ask about that. But again, we have that pest and prey cycle that the voles may come in and do a lot of damage, before they get a chance to be taken. And then it depends on what your neighbors doing and how effected the birds are. This is a question that I our new vertebrate pest person, Brianna Martineco in Napa who she took my office, not my place, right. So we we about a weed scientist. And one of the questions I've asked is, you know, how much of an area around the vines? Do we have to keep clean, so that the birds have a chance and the voles stay scared? You know, that's kind of question, you know, especially as an emeritus, you can ask these questions. And, you know, let the new people answer them. You know, the other thing and I've talked about this is in a rare occasion, you know, one of the things that we do you see people, anytime I'm out in the field later in the season, I talked to a grape grower, while we're out there, they're pulling those leaves off so they can get more air movement. Well, if you get some tall weeds like that, you know, the oak grass that was growing, you know, are you going to have restricted air movement? Are you going to have higher moisture content? Is that going to increase your pathogen pressure it can, doesn't always happen. The other thing too is having, you know, high grass can cause in frost prone areas, you know, if you're not getting that radiation from clean soil, and that's in the middle, not so much under the vines, you know, we can have that and sometimes on young vines near the vine itself, getting that reradiation, but again, you know, as I like to tell people, you're not going to have all these situations, and it's not going to be every year, you know, some years you're doing things you may not need to have weed control that year, but you don't know until after that year, you know, and now and I'm not I'm not a pathologist, I'm not an enthramologist, I'm not a viticulturalist I'm a weed scientist. But you know, there's been some indications that some weeds that are growing and some of the we plant and some of that we don't are having a, you know, an increase in pathogen plant pathogens that are moved by certain insects. tikka pirate likes legumes Well, you know, especially in some of our low nitrogen situations, plants that produce their own nitrogen, like Bird Clover really tend to like that situation because they have a, they have a built in advantage by making their own nitrogen. So we can in some vineyards, we can see a high population of bird clover, which may or may not cause an increase in tikka, which could cause an increase in red blotch. So, you know, when you think of weeds just specifically for competition, like when I talked to master gardeners, I say, you know, if you're growing carrot, you know why you do weed control because you want a carrot. But when it comes to a mature, you know, a 10 year old vineyard, really hard to see that weeds are going to compete on an everyday basis like they would with an annual crop, but there are other reasons why we do it. Ease of harvest, and I talked about, you know, in talking with some pruning crews, right, you know, if you have weeds growing in when you're pruning, and I tell people, if you have an area that takes an hour for let's clean, takes a pruning crew an hour to prune, if there's a bunch of weeds that they have to move around and get around, and it takes them an hour and a half. So your labor costs have gone up 50% Yeah, these are the kinds of things that as a weed scientist, I think about I tell people I really want to know two things. And when we're when we're taping this, it's the right time of year. I only know weeds in college. Basketball. So these are the only things I really know. So, you know, and I've had other I've had, you know, some people sit down and say I should have known that you have to worry about, you know, disease pressure, and getting labor contractors. And I just think about weeds.   Craig Macmillan  20:16  And let's go back to another technology that we touched on snow plows, French plow, that's a very old technology. And, you know, we just mentioned that what a plow does is it turns the soil over, so it buries the weed plants, especially when you get into the right time, what conditions are appropriate for using a French plow? What conditions maybe it's not gonna work so great.   John Roncoroni  20:41  French plow, I mean, you know, the USDA says that, you know, doing something like that the soil is never good, and you're going to mess up the microbes, especially if you're working on that lower area. But as far as just from a weed perspective, if you're dry farming, a French blot works fantastic, right? You're not looking for, in fact, you're trying to discourage as many roots at the top as you can. So doing using a French plow when you're dry farming, it's fantastic. We don't have you know, a lot of dry farms where we are looking at trying to have more consistent harvest and looking at consistent income, where you know, dry farming were at, at the will of the of the weather, that's another talk for another day with people who are doing marketing and know viticulture are better than I do. But see, I've seen more French plows as people have gone back to mechanical in the last few years, and I have in the past think there's a lot more viable options, when you're actually looking at doing some drip irrigation, then they're just by number a lot more viable options. Just by new having new machines coming out then the French plow but I was a dry farmer, my weed control would be French plow under the vines and disk in the middle because everything's you know, maybe having a little cover crop to get more penetration. But, you know, the farther north I lived, the more water penetration I would have. So I'd get more rain.   Craig Macmillan  22:00  So let's talk about drip irrigated vineyards. And you mentioned there's a suite of technologies, some are new, some are old, what are some of those technologies that have worked well in a drip irrigated vineyard?   John Roncoroni  22:12  When I got to Napa in 2007, sustainable at that point meant post emergent only and for those kind of funny now is roundup on the right no preemergent no cultivation and we were drip irrigating, we were keeping those roots at the top so we can drip irrigate. So that's where a lot of that came from. Now, you know, using something like a blade using a little Dustin with those moving things, anything that's sort of like you don't want routine, right? Again, I don't I'm not a vitaculturalist. But roots at the very top are not great, right, you're not probably irrigating correctly, if you're getting a lot of roots at the top, but you don't want to get too deep, where you're getting some of those main roots with cultivation. You know, that's one of the reasons that we do have drip irrigation. At that level. You know, I've talked to people who weren't using cultivation and ask them why their drip irrigation lines weren't closer to the soil so they're gonna have less evaporation. One of the things that we get into with grape growing or anything is that you do things because you've always done them that way, we are cultivating that we do need to keep that drip irrigation at at a higher at a high level. But I think any of those anything that's not just completely disrupting the soil. One of the things that I would like to see with with mechanical like a blade is using some electric eye, AI technologies to get closer to the vines. But right now we have to really, you know, it's all mechanical, right? If we can have these machines down in Salinas, that are taking weeds out from in between lettuce, we don't have to be nearly that technological, to get weeds right around the vine without hurting them. And we have a little bit more leeway with the vine than we do with lettuce. Even though you lose a lettuce plant here or there. You're okay. You don't want to lose too many vines. You know, I think that that's where one of the reasons that we could use more technology. One of the things again, my doctor Moretti up at Oregon State and also lenses masky. Back in Cornell, who they were both at Davis at the same time, Lynn as a postdoc, and, and Marcelo as a as a graduate student, they're working with electrocution of weeds, I think it's what they call it. And it's not just burning them off, like you would use electric light with a flamer. It actually sends electricity down into the roots. So it's, he's working on it mostly in blueberries. But the technology I just I saw his presentation at the Western society Weed Science meeting just a couple of weeks ago in Denver. It's an interesting technology. If you're like having a transformer on the back of your tractor. It's pretty cool.   Craig Macmillan  24:35  There's a there's a lot of potential here in the future for improving what we're doing now.   John Roncoroni  24:40  Oh, yeah. And I don't know how like electric is going to fit into this. But and this is the problem. We ran into herbicides. Anytime you use one technology over and over and over and over and over, you're going to choose for weeds. If you constantly mow under the vines or anywhere, right without some soil disturbance or application of herbicide, something Like Melva, low growing weeds, they'll adapt, right nature will find a way. So the biggest thing we have to do is whatever we do just don't do it all the time. That it's the right message. One of the things that I think we want to talk about was under vine cover crop. It is something for me, I've been trying to push under vine cover cropping for so long. And the problem is, is that because the seeds are expensive, I tell people that one of the one of the plants that I pushed, just because I liked the way it worked, and what I've seen is Zorro fescue. That's a brand name, it's it's rat tail fescue, you see it growing as a weed a lot of places, one of the things I like about it is that about the time we start irrigating, it's dead, it's the nest, and you can discover you can turn it over, because once it's gone to seed, you can mow it all those things. It's a it's a self receding cover crop problem is that because the seeds are fairly expensive, we planted at about eight to 10 pounds per acre and sometimes mixed with Blendo broam, which grows a little higher and stays a little greener longer than I like, because it can be some competition for water. But that's oftentimes keeps it down. But the problem is, is that first of all, how do we get it on the vines, I find people putting it out by hand, because we haven't adapted for the cedar under the vine. Second of all, it starts to reseed itself at a fairly high rate, sometimes 50 or 100 pounds the next year and the third year. So I tell people, if you can't give me three years to make it look good, then let's not start because oftentimes, you know, we started and it looks like it's not doing a very good job the first year, and it doesn't look very good. And some people who don't ask people who make decisions about vineyards who maybe work other places, then the vineyard don't like the way it looks. Right? Right, and we move to something else and they end up spraying it out or cultivating it out.   Craig Macmillan  26:55  Then this is an example of modifying the environment to address this problem and modifications to the environment take time.   Speaker 1  27:03   And this is what intrigues me about regenerative agriculture. I know this is a whole nother subject for someone who probably but as a we, as a plant biologist, and ecologist, you know, actually choosing plants that we want to be there without causing problems. Again, the voles, the legumes with maybe some other virus problems can be, but I think choosing these plants is going to be so important. But you know, it's interesting, I had someone call me and they wanted to start using regenerative agriculture. And I told them, you know, your first three years are going to be really hard I go, you have to choose the right plants, you're going to probably maybe even have some reduced yields. And they said, Well, why John, because my friend has been doing it 25 years, and he's doing great, because his soil knows what to do. So anytime we make that transition and transitioning to this under vine cover cropping. And there has been places in the past where we've tried to use a listen. But listen, because of insects and some other things. The problem with alyssum is after about three or four years, it gets to be about four feet thick. It's one of these things, it's good for a while, but after it kind of takes over, it can cause some holding in moisture and doing some other things. I mean, some people again, depending on how fertile your soil is, you know, some places it may not be a problem, but we have to look at it on a vineyard by vineyard scale. And that's been the thing about herbicides is you don't have to think about the basically the vineyard by vineyard,   Craig Macmillan  28:24  We're basically at a time but don't ask your boys. Is there one particular thing that you would say to grape growers on this topic of let's just say mechanical?   John Roncoroni  28:34  On the whole subject of weeds, Craig, I just want to say that they need to know their weeds better. Right? I know it sounds like I always have a chip on my shoulder. And now that we have to right thing about glyphosate is they really didn't have to think about didn't have to think about their weeds. So there's there's two things I want to know we're almost out of time, but we are out of time. But there's two things I want to say about this real quickly. And I know it's mechanical, but those people who are still using chemicals, they could do a better job. Right new nozzle shielding timing, think more about put as much time and effort into thinking about the weeds as you do about insects and pathogens. Know your plants. Don't just say I'm going to do this. It doesn't matter what the weeds are, know your weeds, know their biology. Know the timing, no matter what kind of control you're doing. And then once you do, get the best tool, like if you are still spraying in certain situations in certain vineyards, use new drip reducing nozzles, use shielded sprayers when you do mechanical, you know, don't just get that old thing that like you said, that's been sitting out in the back, right? Look at the kind of machine that you want to use what we do have, I think when it comes to weed control, the whole industry could do a much better job. Okay, one of the things that I put a slide up one time and I said look, I understand pathogens first and then insects, and then weeds and someone got up and corrected me and they said John, that's wrong. I said Oh really? They go? Yeah, it's pathogens, insects, fertilizers and weeds. Right so weeds and when it comes to weeds being third weeds are not just third weeds or a distant third. They only think for me about all the cons Diversity that's happened is that people have to think about weeds again, they have to go back to knowing what we knew before that before they all started using chemicals.   Craig Macmillan  30:07  So that makes a lot of sense. Yeah. Our guest today has been John Ron crony. He is Weed Science firm advisor emeritus with UC Cooperative Extension, UC Agriculture Natural Resources. I followed you from afar for a long time. And I'm very excited to get you on the podcast. This has been a great conversation. Yeah, there's so much more to talk about, and I'm sure that we will, we will reconvene at some point.   Nearly perfect transcription by https://otter.ai

Dr. Drew Lyon is a Professor and the Endowed Chair of Small Grains Extension and Research for Weed Science at Washington State University in Pullman. Prior to moving to Washington in 2012, he spent 22 years as a Dryland Cropping Systems Specialist at the University of Nebraska at the Panhandle Research and Extension Center in Scottsbluff. His endowment is from the WA Grain Commission, so he spends a lot of his time with wheat growers, but most of them also include pulses in their rotations. Our discussion mostly focuses on integrated weed management of chickpeas, from cultural practices to herbicides to biologicals. “We do have some effective herbicides out there. In this part of the world nature doesn't always provide us with the moisture at the right time to get those products activated and going, that increases our need to use things other than herbicides for weed control. Because we've had 30 years of really effective herbicides that's the first place a lot of growers think. But I think we're gonna have to start thinking more about other approaches, things we used to do 40 and 50 years ago before herbicides were so effective.” - Dr. Drew LyonLyon has seen herbicide tools come and go, both in their effectiveness and their availability. Because of this, he is a big advocate for an integrated weed management program, which he says all starts with trying to grow a competitive crop. He shares that there are also things that can be done to try to manage the overall seed bank of the weeds on fields. Cover crops, he says, can also be helpful with weed suppression if you have the moisture. When all is said and done, Lyon's advice on weed management comes down to three basic principles: don't get weeds started, do everything you can to grow a competitive crop, and always be changing things up.“Prevent weed problems from starting. If you don't have certain weeds on your farm, make sure you don't get them… Do everything you can to grow a competitive crop…And then the other thing is to change things up. Anytime you do the same thing over and over again, you tend to select for those weeds that do well in that system…Human nature is that we like to stick with things until we break them, but that's the recipe for getting weed problems” - Dr Drew LyonThis Week on Growing Pulse Crops:Join Dr. Drew Lyon is a Professor and the Endowed Chair of Small Grains Extension and Research for Weed Science at Washington State University in PullmanDiscussion of past, current and future integrated weed management for pulse crop producersRe-visit Dr. Drew Lyon's discussion on harvest aids from season one in episode 12Growing Pulse Crops is hosted by Tim Hammerich of the Future of Agriculture Podcast.

This episode gets into the weeds with James Westwood a professor at Virginia Tech whose research focuses on parasitic plants, plant communication, and weed evolution. He's also the lead author of “Weed Management in 2050: Perspectives on the Future of Weed Science.” 

Listen to our first podcast of 2022, where we discuss weed management techniques, old and new, and the tools being developed to achieve food crop yield optimization with Vipan Kumar, Ph.D., Assistant Professor in the Department of Agronomy at Kansas State University. Weeds can reduce food crop yields by more than 30%.  In this podcast, Kumar discusses the ways in which this problem might be solved when the need for food production will continue to increase, and the challenges caused by climate change create a moving target.   Transcript: “Diversity is the key to Sustainability; Challenges and opportunities in the field of Weed Science”.      Diversity is the key for sustainability. You keep doing one thing again and again you will see a problem that we have seen in our herbicide based methods or weed control.   Something to chew on is a podcast devoted to the exploration and discussion of global food systems. It's produced by the Office of Research Development at Kansas State University. I'm Maureen Olewnik, coordinator of Global Food Systems. We welcome back co host Dr. Jim Stack Professor of Plant Pathology, weeds can reduce food crop yields by more than 30%. These interlopers compete for resources including soil nutrients and water. We attempt to control weed growth through chemistry, but over time they manage to mutate, overcome, thrive, and adjust to given management techniques. So how is this problem solved when the need for food production will continue to increase and the challenges caused by climate change create a moving target. Today, we will hear more about weed management techniques old and new. And the tools being developed to achieve food crop yield optimization with Dr. Vipan Kumar, Assistant Professor in the Department of Agronomy at Kansas State University, I want to welcome you Vipan would like to before we get started in the technical side of things, just get a little background and understanding of who you are and how you got to the place that you are today as far as your professional interests go.   Sure, So my name is Vipin Kumar, I'm originally from India. I did my bachelor in crop science, but finished in 2008 from Punjab Agricultural University back in India, in the state of Punjab, it's a Northwestern State in India, mainly known for wheat production and rice production. And it's very big in ag, Punjab state. So, my original goal was to help communities there, especially the farming communities to management practices they are doing so I did my bachelor there. And then I started my master actually mastering Weed Science in Pau 2008, fall 2008. But somehow I was also interested to come abroad and expand my education here in the States. So I was looking through some programs and during that time, I got to know there is a master positions open in Louisiana State. So I I applied there and I got invited and came over 2009 That was summer 2009 started my graduate research assistant with LSU, Louisiana State, Louisiana State University. So that program was specifically looking for someone who can help growers in terms of managing their irrigation water irrigation scheduling, developing some crop coefficients for the cotton prop in North East side of Louisiana. So I was based in actually a research center. It was in North East Louisiana, about five, four or five hours from the main campus Baton Rouge. So my whole research was on resource center and I got to know very few people there but I had a very excellent project to work with. So during that time, I was doing a master I got interested in Weed Science because wonderful. One of my committee member was a weed scientist. He was the superintendent with the research center and he was on my committee and glyphosate resistant Palmer Amaranth was kinda getting a lot of attention during that time in codon. So during that conversation and meeting with his students, I got interested in wheat science. So finishing master and then I started applying for PhD program. So I think during that time, there was not a whole lot of opportunity because of the economic constraints, but I found one position in Montana State University 2011 So I started my PhD 2011 in Montana State University, Bozeman, the whole my dissertation research was focused on herbicide resistant weeds, mainly Tumbleweed Kosha, looking at, you know, characterizing herbicide resistance evolution, how we can manage in terms of what strategies growers can use to control herbicide resistant Kosha in Different cropping systems. So, that was for four years I spent there and then just immediately after finishing my PhD, I started my postdoc there and two year postdoc in the same program in Montana State. So 2017 I got here at K State got this position, where I am in his as an assistant professor in Weed Science. Part of my responsibilities. I am 100% researcher. All the focus is on developing integrative weed management strategies for western Kansas. Looking at herbicide resistance evolution in weeds, what are the novel and innovative strategies we can come up for our dry land are no till dryland growers in western Kansas. So that's I have been doing last for more than 40 years in Hays, Kansas. And a little bit history on this tradition. My predecessor, Dr. Phil Stallman, he had spent 42 years on this role. He was kind of He's like one of the pioneer in herbicide resistance management in High Plains specially in dryland cropping system in Kansas. So right now leading a statewide program, research program and little bit outreach program because I've been involved with a lot of growers here are the my appointment is not extension or no extension tents, but the been doing some extension as well. So that's kind of in the nutshell, what I'm doing here.    That's great. Okay, well, thank you so much for that overview. That's helpful in me understanding a little bit more about what it is you're doing in reading through some of the information I found on your website about what you do, there was a lot of discussion on no till and the impact of no till on managing weeds and that type of thing. Can you tell me a bit more about what that term means and how it impacts the growing period?   Sure, since the dustbowl period, the soil conservation practices have been you know, taken place among growers in the main reason was those soil conservation practices were to conserve the soil and other resources for longer term because soil erosion in these areas, especially the Great Plains area, or High Plains area was pretty obvious. And because we control it was generally achieved by tillage. So folks still the ground and control the weeds in history, if you see that's like number one method it used to be and then USDA NRCS folks came up with this idea of conserving the soil not to till the ground just to preserve the soil from erosion as well as not to blow the surface soil where we have fertile soil. So, so no till is basically a concept brought up after the Dust Bowl period and got adopted by growers throughout the Great Plains. And no tillage equipments also got, you know, into the market after that like no till drills, no till planters, that growers don't have to till the ground to make the seed bed they can directly go and plant or drill their crops. And this idea or concept was achieved with the chemical weed control. So if you look at after 1940s, when the this chemical era started, like the two four D came into the market, or any other cleaning herbicide came into the market, one of those early products came into the market grower started using those and they found very convenient to kill those weeds and not till the ground. So this chemical era helped to adopt that concept of no tillage in High Plains as well as in throughout the Great Plains. So mostly what growers been doing is they don't tell the grounds they clean their fields before planting and after planting and in season crop by using chemicals and by using herbicides, so it's kind of serving to purpose they're controlling the weeds and they are also conserving the soil. Another aspect of doing no tillage is to conserve the moisture. We are in semi-arid regions our annual precip is not that great. If you look at historically we are between somewhere between 12 to 24 inches, you know depending on the place where you are in the Great Plains so doing a no tillage practice also helped conserving the moisture throughout the winters time. So whatever the snow or the moisture comes, if you don't do the ground, you know it stays there for the subsequent crop to plan and have the crop in place. There are two things basically conserving the soil and conserving the moisture that no till practice came into existence. But however, I would I also like to emphasize over the last 1015 years, what has happened is because we have relied too much on chemicals, too much on herbicides, and we are seeing evolution in weeds, they are developing or evolved resistance to these chemistries, what folks have been using in our systems. So herbicide resistant weeds have really, really become a threat to this Nortel production system and chemical industries are struggling in terms of bringing new chemistries into the market, because there is not a whole lot of investment going into bringing a new motor factions, especially from herbicide standpoint. So the dilemma is to control those herbicide resistant weeds, we need alternate strategies, alternate methods of weed control. So that's where my role kind of come into that where that fit is how we can combine different methods of weed control, including chemical or non chemical, and come up with some sort of sustainable system that can go in longer term.   Yeah, if I could follow up with a question. How prevalent is this problem globally?    Herbicide resistance globally, it's, it is the number one problem for Weed Science communities as well as the grower community. Wherever folks have been using herbicides, we have been seeing increasing trend after 1980s, we have been seeing exponential increase in a number of cases of herbicide resistant weed population being reported, there is a website called Weed Science dot O R G, that documents every single case been reported to the world. And if you go to that website, you will see after 1980s, that graph has just jumped to the highest level. And it's not only one herbicide, it's basically, you know, all the available herbicide motor factions, we have reported case of resistance somewhere in the world. In the US, we are leading in that graph, country wise, in terms of herbicide resistance, the complicated issue is okay, one time a herbicide fails, for example, glyphosate. So folks start using other herbicides or other mode of action, but now been doing those things, we have been seeing multiple resistance in our weed populations. So resistance not only to one herbicide mode of action, but 23456, even six herbicide mode of action resistance in those weed species. So that's the challenge that we are having a limited options in terms of chemicals.   One of the quality parameters for seed, like the grains and things like that is the number of weed seeds that are also in with the grains. Is that a significant way of moving herbicide resistant genotypes around?   Yes, recently, what happened has most of our soybean, you know, most of our corn, we export to other countries. And there has been international standards in those products. And there's inert material and weed seeds are one of those standards. And recently, we have got email from our society, as well as USDA that come up with the plans how we can minimize those weed seeds in the crop seeds. Because some of the Chinese importer, they have stopped taking some of our soybean because of the big weed seeds present in those crop seeds. So it's a function of what is escaping in those crops, what is leaving in those crops at the time of harvest what you're harvesting with. And that's ultimately making those crop quality lower and making those export important difficult. And it's not only that they have they have also raised concern that hey, we don't have this, let's say big weed in China, you are sending herbicide resistant pigweed in our ways. So that's the hurdle with the growers how to sell those because the quality is lower in terms of having weed seeds in those. Those greens.   Yeah, so you mentioned some, weed genotypes with resistance to five, six or more chemistries. What's the strategy then? How do you get on top of this?   Yeah, I feel fortunate and excited some time that I'm in the field that where there is a lot of growth, there's a lot to do. I don't know if you have probably noticed that recently, a Weed Science area we have so many openings, so many positions coming up in industry as well as in academia and public sectors. And the reason is that we are struggling with these issues of resistance and crop weed competition in different scenarios. So, you know, considering that we are getting, you know, way back in terms of herbicide options. Industry is not coping up with the new molecules in the market. And we have more and more cases of resistance. So the shift of the research or read science research has gone to looking at non chemical strategies, what are the non chemical strategies we can bring into our system? So historically, as I said, folks used to do tillage. But in our system in Great Plains, High Plains, that's probably not a good recommendation, if you want to give folks will not like that, because we've been promoting that no till system for decades. And that is number one challenge. But in other areas, tillage is helping and it's helping those folks controlling those herbicide resistant weeds or multiple system weeds. Another approach we are looking at, what are the ecological tactics? How about the crop weed competition, how we can make our crops so competitive against weeds, that we don't have to rely too much on chemicals. One example I can give that is ecological method we are testing here is cover crops, how the cover crops can come into the system, and helps pressing those weed populations and reduce the seed bank. Again, these are not these ecological tactics don't work like chemicals, but they have a fit in our system. If we can, let's say suppress our weeds from 100 100 weeds to 70 weeds, there are still benefit having that. And you can add with the chemicals method of weed control. So that's just one example than other methods, we are looking as a non chemical methods or harvest weed seed control, that new thing is kind of getting a lot of interest among growers and researchers throughout the globe. So when I say harvest weed seed control is basically a technique when you're harvesting the crop, you have weeds in that crop, so you are harvesting the crop and you're also collecting those weed seeds. And then either you are destroying those weeds by crushing them when they're coming out of the Combine that's called harvest wheat seed destruction or you can put them as a CEF as a narrow line called chaff lining behind the combine. So this concept was brought up or discovered by a grower actually in Western Australia in a dryland wheat grower actually, just similar to what we have in western Kansas, he was struggling with the rigid ryegrass, multiple resistance to the rye grass. So what he did is he started destroying those rye grass seeds when he was harvesting wheat. So over the two, three years when he did that, he found that he reduced the seed bank, he didn't have to deal with that problem with the chemicals. So but in US or in North America, that technology has just arrived. And we are the first one in classes we have bought that destructor and Jeff minor. And we have got some USDA wants to test here in High Plains, how that's going to work in our system. I'm just giving example that those are the kind of approaches we are looking at it from the future work. Third thing which I really like to touch base is the proceeds. And that's the coming future of the Ag digital agriculture or Smart Agriculture. You can name it differently, but that's happening. So from a weed control research or weed control perspective, precision agriculture is another way to look at these problems or herbicide resistant weed problems.   So how specifically does the Precision Ag is it about applying chemical where it's needed when it's needed? Is that the strategy there? Or?   Yes, that there are different aspects there preseason agriculture or preseason technology is what we are, but I can envision is, you know, it can help us at least doing field mapping with to start with if we can detect early detection of herbicide resistant weed population in a farm. And then we can develop strategies accordingly. And again, then the next level of proceeds and that could be a variable rates of herbicide application or spot treatment. We don't need to spray the whole farm maybe, but just a little patch where we have herbicide resistant weeds growing. So that's where we can, you know, have precision ag tools helping us in the future if we have a good set of data, especially if you have good algorithms and good database, we can identify our pig weeds or Kosha or any other weeds in our crops, I think that can help making making your decisions or plans for weed control.   Yeah, thank you. Sorry, Maureen I've been dominating.    No, that's okay. It was you know, as he was talking about some of the methods that they're looking at it. It took me back to my previous life. Were working in the food safety area, we focus heavily on integrated pest management, it sounds to me like the directions that you're heading now that the chemicals are not doing what they're supposed to necessarily be doing. You're looking at these integrated systems of trying to control those weed productions from a whole variety of different areas. And it may be that there are packages or approaches  that can be taken based on location based on crop type based on a variety of other things. But you will have that group of tools in your toolbox. Is that am I interpreting that correctly?    Yes, yes, you're right, you're on the same page. The things are like with this herbicide resistance management, it's all economic aspects. Economy drives these things, the farmer economy, when they are going to make their weed control decision, they're going to look at what herbicide how much it takes, what is the rate? What is the cost. And if you see, like with the roundup resistant weeds, folks have been switching to other chemistries which are more expensive, and having more other issues as well as like drift to other crops or drift to other organisms from environmental standpoint. Also, chemical control is kind of getting ahead. In terms of some folks, they don't like some chemicals because they are hitting their other organism or other crops sensitive crops. And the second is, economically Is it viable to use that chemistries, for example, you know, most of the folks most of the industry, you might notice these days, they're giving a talk having a true two or three different herbicide mode of action in a tank, they have a pre mixes available two to three actives in those pre mixes. But those are very, very expensive. Those are not cheap products to use. So the idea with the growers with the lower commodity prices, they don't want to put those high expensive herbicides at especially when you are doing in a fallow weed management, you're not getting any output or any return in those fallow fields. So to make the system more economical, you need to think about where my money is going in terms of inputs, those herbicide applications and in fallow systems grower used to spray like three, four times in the season. It's not like one application, and they're done. They used to spray three times four times. And you can imagine like 5000 acres spraying three times $10 an acre, that can multiply pretty quick. So that's where I think the folks or the weed science community is thinking to bring some of those cost effective programs or cost effective management strategies in our system that not only helps pressing this problem or suppressing these weeds, but also give benefit to the growers, and the environment and ecology or agro ecology, like a cover crops. So we are not just thinking integrating cover crops for weed suppression. But we are thinking that cover crops can help suppressing weeds. It can help you know fixing nitrogen, it can help improving the soil quality soil health. And it can also be used for grazing purpose to the animals. So there is a livestock integration as well. So we have we are thinking from a system standpoint that can help folks to be more economically viable.   This next question is kind of out there as it's taking us probably outside of your major focus at this point. But I've done a little bit read a bit of reading recently on the land institute and some of the work they're doing in Salina on perennial grains. Have you looked at that at all or have any thoughts on perennial brains? And if there's any value to that and what impact it would have on what you work on?   Definitely, I have not personally looked at that system yet. But I've been hearing that quite a bit. And we have a cropping system specialist here in his he's been talking one other day was giving a presentation on that side of it. But I think again, I would like to emphasize that Perennial system or perennial grain springing into our system is basically improving you know, our our ecosystem and also increasing the economic value of the products as well as the farm profitability overall. And some of the work being led by cropping system specialist here or agronomist here. Also looking at those forage species or forage annual forages or biennial forages or perennial forages as a part of the system that can integrate into our system. So, from Weed weed management side of it, I think that would be a win win situation that if that species or if those grains or perennial grains can provide that kind of weed suppression benefits what we are getting from other cover crops. I think that's what we need.   So one of the reasons we care about weeds as the as we do the other pests as their impact on production and grow the crops for to feed people, we grow the crops to feed the animals that become the food that they feed people. Are there reasonable estimates of the economic impact or the yield impacts that you know, general rules of thumb? I know there, there are no exact numbers, but what what are we talking about in terms of scale of impact that we have on food production, but then also, what having herbicide resistant weeds contributes to that?   Definitely, there has been several reports in different crops. And I will just highlight some of the examples here for Kosha or, or Palmer Amaranth. Those are the prevalent species here in western Kansas or central part of state, if you like, look at some of the reports on Kosha. previous reports from my previous predecessor and other colleagues in other other states, they have found Kosha is quite competitive. Irrespective of resistance, let's say there's no resistance in these species. These weed species are very, very aggressive, very invasive. They have good traits, good biological traits, to compete very well with the crops. First, you need to understand that the biology behind those weeds, that's why they're becoming more and more troublesome problem for the folks here. So in terms of yield impact, I would say Kosha, let's say you know, you leave the kosher season long infestation in a crop like that the sugar bee does the least competitive crop in among all those crops, we grow in the northern or central Great Plains by up to 95% reduction in those sucrose yield as well as the beat heels we have reported. We have seen in the literature since 1970s 1980s. Wheat 20 to 30%. Yield reduction, going to be the kosher season long infestation, when I'm saying the Kosha is like moderate densities 40 to 50 plants per square meter, if they are present, they can do that 20-30% of damage to the yield big waves, they can choke our our sorghum. So one of the worst fields I have seen in my lifetime here in western Kansas is sorghum because the folks they don't have option, there's not not a single effective option that can go with for controlling pigweed controlling Palmer Amaranth in sorghum, especially when the sorghum is above certain stage, like 30 inch tall, there's no label chemistry to go with controlling pigweed. And that's the time I start getting calls from growers, hey, our pigweed is this much our Milo is already two feet tall, can I spray Dicamba that's the off label you cannot and if you do it, you will hurt you leave you will that will cause a crop injuries that will cause reducing the grain quality. So yeah, really impact. I mean, there's a huge impact. And you can imagine now if those species are resistant, and you are putting the chemical, and they are surviving 70% of those ceilings are surviving. And you know, going up to the seed production, you can imagine that you have put the cost to control it. Plus you still have a problem, and there is a double hit there.   Right. That's the double insult with resistance.   Right. So yeah, that's I think that's where we need to be more proactive. And we need to think more in longer term. The growers don't think in a longer term, they think on an annual basis because their budget is running annual basis. They have like let's say 5000 acres, they have a plan for 5000 acre for one year, they don't have a plan for three year or five years. That's where the problem starts. And as I said, economy drives all these things that resistance management. And that's become really, really challenging for researcher as well as extension person to convince folks to do things they're not doing.   You're talking about the aggressive nature of some of those weeds and thought just came into my mind on the genetics of those materials as any work being done at K State on the genetics of some of these weeds.   Yes, yes, we have a weed physiologist, weed physiology lab in in Manhattan. There has been quite a bit of work been done. And yeah, there's all kinds of different genetic mechanisms they have found in these weed species, why they are adapting to these kinds of situations herbicide applications. One example I can give here is Kosha and Palmer Amaranth. They have developed resistance to glyphosate commonly used chemistry or herbicide in our system in Roundup Ready crops. We have seen both species Palmer and Kosha. What they do is they multiply that target gene so they have more copies of that gene with the glyphosate go and target. So what it does is instead of one copy, single gene in they have Kosha has like 10-15-20 copies of that gene. So that Are those number of copies of that gene produce more enzyme, so the chemical cannot inhibit that much enzyme. So the those plants survive those treatments. That's how they are kinda adapting to that glyphosate treatments or other mechanism recently, weed physiology lab in Manhattan, they have found these multiple resistant pigweeds, what they are doing is they have enhanced metabolism. So some of the genes involved in metabolism in those plants, they got activated, and they are just metabolizing, whatever you're spraying. So no matter what, even a new chemistries is not even existing, it can just metabolic metabolite because it's not reaching to the target gene and hitting those targets side. So that is a more fearful thing happening in the nature, that metabolism based mechanism is also evolving in weed species. And as I said, it's a function of the biology of the species like palmer amaranth, very, very diverse genetic background Kosha. Same with very diverse genetic background, a lot of gene pools, they're sitting in those, you know, individuals and they can, they can adapt, and they can evolve to any of those stresses. Among other biological feature if you read about kosher Palmer, both are highly prolific seed producers, a single kosher plant can produce hundreds of 1000s of seeds. A one female Palmer Amaranth can produce millions of seeds. So that many seed production, it has potential to infest more areas, more lands, and keep going if you don't manage them properly.   Is dissemination and equipment. Problematic locally, though, going from one field to the next?   Yes, yes, big weed or Palmer Amaranth. We had a meeting North Central wheat science meeting, talking with the folks from North Dakota, and South Dakota, they have started seeing palmer amaranth, it was not the case, five years back. And that's happening because of movement of equipment, movement of products, like hay movement, or even animal feed, people take the animal feed and take to the other states, and those farmer seeds go with that. And, and infest those areas. So that's kind of tricky, you know, managing those moments is very, very difficult. That's where we kind of emphasize that control those weeds in the field, so that you don't have to deal with in the products. Okay, or, or green or or equipments. For weeds like Kosha, it's a tumbleweed and doesn't need that many it can tumble miles and miles when the wind is blowing. And that's the kind of beauty of that weed species that finds new areas of infestations with the high winds, especially in the high plains, it can tumble, it's very hard to kind of contain that.   How is the contaminated seeds physically removed from the grain itself? I'm sitting here trying to get in my mind if we're going to be selling to other countries, and they've got obviously a lower limit that's allowed in there. Is there some kind of assuming practice or an air movement as the heavier seed goes through? How's that done?   Yeah, I don't know exactly how that will happen. Because this year, we are talking like a bulk export. And folks just take the produce from the field and sell it to the coop cooperative marketing places and I don't know how much storage they have, and it gets pretty big pretty quickly. So that's where we try to emphasize to the grower Hey, you know, if you can manage in the field, that's the best you can do. You don't let it go to the produce or to the greens I see that's where this harvest we'd see destruction is going to have a fared very well that can destroy the weed seeds don't don't don't let it go into the grains and escape folks to get the contaminated grains. And it's not only that in crops like wheat, we have a problem we have a central Kansas growers they've been dealing with awry federal MRI or CT or MRI issues. So those dry what it does is it contaminate it has allergen, so it contaminate the grains when you export to the you know, Asian country, they don't take that because they are allergic to that allergens in CRI. So the idea there is and it's very difficult there's no inseason chemical you can try and control in wheat unless you have herbicide resistant weed like waxy and wheat or Learfield weed where you can spray some of the herbicide and get rid of those grass species. So in those situation against this see destruction can really really help folks not letting those weeds eat grains in the in the crop grains.   Is there a limit in the seed size? Or? I think that new technology sounds excellent for being able to destroy the seed in the field, or the limit that in terms of which species would be vulnerable.   Yeah, yeah, those are all questions we are trying to address here as a future research in Australia, they have destroyed these rigid ryegrass that's quite a bigger size like a wheat grain size of the wheat seeds we are talking. But the things we are talking here like big weeds, very tiny small black color seed and waterhemp or Kosha. They're very tiny, tiny seeds, very small seed seed weeds. As per my experience. I have gotten the unit last Wolsey last fall September and we put together there was a technical team came and put on a combine and let's try that one of the grower field, we took it by miles south of Hayes and run on a grower farm was heavily infested with the Palmer Amaranth. I couldn't see even a sorghum plant, as all Palmer Amaranth. And I was trying to do that. The idea was how that goes, I was very curious how much destruction it can do especially in crop like sorghum, when it's green, and you know, high material, you're going through the combine what kind of destruction it can do, I was very, very curious. But somehow I found that we collected some of the samples out of the combine, and behind the Combine of that destructor I was always amazed to see like 85-90% of destruction is was doing on those Palmer Amaranth seed, those tiny, tiny seed was kind of pulverized. It was like powder form after that. So I was pretty amazed. So I was telling my team of folks from Iowa State and University of Arkansas, we're gonna run this in soybean, corn, as well as sorghum plots in the coming season to see if what it does and what how the crop species or the how the crop varieties also matters, using this technology, not only weed species, and then how the environment impact those results in high plane versus Midwest versus mid south, how things change from region to region, crop to crop, weeds to weeds. And with this, this grant, we have also a Ag Econ person on the team. So I'm going to look at the economic side of it. Because as I said, economy drives everything. And if you're gonna promote this technology, where we stand in terms of economy, is it cost effective? Is it sustainable? So I think I'm telling more future research here. But that's, that's going to happen.   Good. Good. Sounds promising. Yeah.   Pretty interesting, pretty exciting. And along with that, we are also not looking at one tool at a time. Our main mission with this project, which we got funded by NIFA, based on our TFS grant was to having bringing all the tools together, it's like bringing little hammers together. So we have a cover crops early in the season, we have herbicides applied. And then at the end of the season, we're gonna do see destruction versus Jeff lining, and comparing with what growers are normally doing conventional harvest. So there are three different approaches, we are trying to bring in one growing season, to say, hey, early season management with the cover crop, herbicides, late season management, or weed seed management, with this destructor or outlining how they come together as a system, and help growers if they're struggling with some of these multiple resistant pigweeds.   I appreciate your mentioning the seed grant and appreciate you having come to Manhattan to present the results of that work recently. And that information will be up on our website in the near future. We'll have all of those and have those available for anyone to listen to, as well. I'm glad to hear that it panned out into a larger grant. So that's great.   Yes. And that was really, really good support to get that kind of grant and reach out to the folks what they're really looking for the survey we did me and Sarah, we learn a lot. And some of that information. We just plug in our proposal. And it sold out pretty quickly. And to your surprise, and to my surprise, that proposal was ranked number one in CPPM in the country was in that program, NIFA CPPM program and the Secretary with agriculture wrote a letter to the PI. That was excellent proposal to put together for such kind of strategies to look in the soybean system.   Congratulations on that. That's great.    Yeah, that's, yeah, that was really, really a great help from the TFs good Add money in that we could create some data to supplement data for the proposal.   But you know, the phenomenon of resistance is just creeping through agriculture. So it's the herbicide resistant weeds. It's the fungicide resistant pathogens. It's the antibiotic resistant bacterial. And we really need to get a handle on it, if we're going to continue to produce at the levels we've been producing. So I'm wondering if the strategies you're looking at it, if there are some general principles that you think will be helpful in, in the other arenas, as well, not just the herbicide resistance, but in the others?   Yeah, the basic principles, we are looking at the diversity in our system, I think, diversity is the key for sustainability, you keep doing one thing again, and again, you will see a problem that we have seen in our herbicide based methods of weed control, you've been doing same chemistries over and over, we have seen resistance issues, diversity, could be anything diverse cropping systems and diverse, you know, diverse methods of weed control, doing different things, you don't give same thing to that we don't do that best again and again, that that test start adapting to that matters or that strategy. So every year you change that strategies and give something new to the past and head those past with a different approach. So diversity, I think, is the key, what we are trying to achieve with this eating greater weed management system or ITM systems that you bring diversity in crop diversity in your herbicide diversity in your read species, overall system wide. I think that's the key principle we are looking at it. And that can be translated easily to the other disciplines, like, as you mentioned, plant pathology or entomology, not to look at one strategy or one thing at a time, but looking at the system level, where things can be bring and can bring that diversity into the system.   I love this area. You mentioned that there are a lot of opportunities right now for weed scientists. And I look at the agronomy department here at K State. It's been really strong in terms of the scope of capabilities, the expertise that's in that department. It's pretty impressive what they've got within one department. So what if there are students that listen to this the either graduates or undergraduate students listening to this? What skill sets? Would you recommend chemistry? I mean, ecology, what skill sets would you recommend if they want to help tackle this problem?   Yeah, that's a great question. As I mentioned, a lot of opportunities coming for fresh graduates and a lot of weed science positions recently opening up in academia, industry and other public sectors and private sectors. What I see as the weed scientists in this position, the four most important skill sets I can see is the knowledge of field based research, field based Weed Science Research, every fresh graduates they need. And then training of all the plants, science, biochemistry, physiology, genetics are those are specialized area already there. If you can take little bit of that have some expertise, you don't need to be doing five different projects in that area. But if you have little, little component of those areas, that really, really help understanding the problem, you know, from the root stand point of view, but applied Weed Science, statistical skills, how to handle the data, because the future is all about the data. With all this digital agriculture, you're going to tackle with the big data set, how to look at the data, there is a lot of data but what you make of out of the data. So statistical analysis, or analytical skills are also very, very important. And then you can also look at the mysteries in Weed Science, especially herbicide you need to know what you're doing and what you're tackling with. Because again, 70%, more than 70% of the calls the growers give me is they asked me the option herbicide option. They don't ask me, Hey, should I try this cover crop? They simply asked Hey, can I spray they can buy glyphosate is not working? How expensive? Is there a generic one? Is there a lower price one what is the formulation? All kinds of chemistry related question will come if you are going to go to those real world situations like applied weed sign, you know Precision Ag or engineering side of it. If you can learn some of the skills. I think that's the benefit as well, because that's happening right now. Preseason agriculture tools, a lot of weed science folks, they have started really using it and implementing into their programs. And that's going to be the future. A lot of the industry investment is going into that digital agriculture, especially from pest management, especially from weed management perspective. So those are some of the skills I just listed is applied Weed Science, applied field based research, chemistry knowledge, little bit of those physiology, genetics, biochemistry is knowledge, statistical analytical approaches. And procedure neck, I think, if you have little bit of all of those, and you can sell yourself, you will get the job, I'm sure. But for the weed scientists, as far as I know, yeah.   Thank you. Thanks.   Great question. And great, good bit of information for the students here on campus to file away as they think about what they want to work on. Yes.   And I think I would also encourage undergraduate students if they are interested in in ag and if they are specifically interested in in weeds or any other pairs, they should do some project, they should contact folks on Main Campus or research center to get involved and to get learn how to handle the project or what to do in terms of research and how the research is conducted and how the data is handled. That's pretty basic. But there's quite a bit of learning before you get into your graduate schools, or Masters or PhD. If you can do a little project in undergrad that'd be really, really helpful.   I enjoyed this conversation quite a great. One other big challenge on the horizon is, of course, climate change. And a number of studies done on how it's impacting the migration of plant populations and impacting fertility of some plant species, things like that it does that come into play here in terms of weed management?   Yes, exactly. If you talk about climate change, or drastic changes in environmental conditions, weaves are one of those first pieces who will adapt to these changes, because they have highly diverse genetic background. And they have already been doing that molecular weight science program in Colorado State has been looking at Kosha from different angle. So they're trying to sequence the whole genome, they're trying to characterize some of the genes, good genes, they call it good genes, which are helping this Kosha to adapt cold treatments, or frost or drought, or heat, or salt, or even herbicide resistance, how those genes can be incorporated into our crops to make them more resilient for the future. Okay, so that's kind of angle to look at these weed species, we have that gene pool in those species, why don't we characterize and understand then how, and what they can do when we incorporate those gene in our crops for the future crops that can be resilient to the, to the these changes in climate environment. But as I said, changing climate changing environment, adaptation is going to be happen, evolution is going to happen in those weed species. Along with that, what's going to happen is interaction of the chemistry with the plant and the environment is going to change. And that's very critical to understand the efficacy of some of the chemicals we are seeing now probably will not be there into that future environmental future climate. Just because plant adapt, and they adapt differently, they have TIG cuticle, for example, the chemical may not penetrate that cuticle in the future, and cannot give you 90 95% control versus less than 70% control. So the efficacy is going to change or with increasing temperature or increasing carbon dioxide, C three C four species who's going to win and depending on those weeds species are those C three or C four, the shift will happen. And there'll be lot to play with climate and the principles of precipitation, how the precipitation change globally, some of these root shifts, also gonna share some some of the prediction has been done. Okay, if Great Plains start getting more rain, for example, we start going to see waterhemp coming this way, in Great Plains, if it's going to get more drier. Kosha is going to start going towards Midwest. There are predictions happening. And I think that's true, based on the biology of those weed species and based on the history of those species, how they have infested, and they have line ated themselves in those geography based on the climate.    Vipan, you had talked about when you were first over in the US you were working in Louisiana State working on cotton. And with climate change, I'm sure that that impacts this we're seeing cotton work its way into Kansas cropping Are you seeing? I mean, I know your focus is on the weed side of things. But are you seeing some of those other types of crops moving in more and more into these areas, some of the crops that we're used to moving Further north and having some new impacts of weed stress and that type of thing coming in with these new prompts.   Definitely, with changing things with the changing environment and climate, these things are happening. And we need to be very resilient in terms of adopting those things, changing things like we were doing this faculty meeting other day and prioritizing our missions for the unit other days. So one of the priority we have have for next 1015 20 years is to look at alternative crops, new crops, basically what folks need, provided that our conditions get changed, our environment gets changed, we get less peace, we get more dry land, what are the alternative crops, things like barley, millet is number one can be adapted to in the West, that has not been expanded. There's a lot of potential for that crop. There's a lot of potential for canola in the southwest Kansas. That has been happening already happening expanding. In as you mentioned, cotton, yes, it has gone up. It was not the case five, six years ago, but it has gone up 300,000 acres of cotton in Kansas, can you imagine. And then over the top of that you can see the changes, the commodity Commission's have started funding some of the positions for those areas as well, they are looking for a pattern specialist in Kansas, they can support this. So things have been changing with the climate change with environmental change, as well as you know, other changes. And one thing I can I can say for sure, from a read science perspective, you bring new things, new crops, for example, that has long term impacts on our weed population. Some of the previous studies, long term studies, 1020 years long term studies have shown that the crop rotation in competitive crops and what kind of crop you're growing, will have ultimate impact on those wheat population. If you are growing, for example, let's say highly competitive crop like corn, or could be any cereal grains, that grows pretty aggressively, it can shift some of those wheat population over the time, a study done in Nebraska has shown that you keep doing this corn soybean rotation, you will see more and more issues weather resistant Kosha and resistant big weed, but you will bring cereal into the system, you will lower down some of those resistance issues is because the crop competition expressed those cycles of those weed species and don't let them produce seeds. So weight shift is going to happen when these crop change is going to come into play in our system. But as again, I said we have to be very resilient and proactive, like things are happening. And it's going to happen, especially from climate change standpoint. So we need to be resilient, or what alternative crops we can grow. And we can still make these folks or the growers more profitable in the future. Considering all these constraints, weeds and other pests we will have.   Yeah, I'm hoping for mango and oranges.   I'm not sure on that. One more. Yes, really,   This has been a really a fun and interesting discussion. Well, thank you so much for your time. And thank you, Jim, for joining us as well. Do you have any final remarks, or any questions you might have for us before we sign off?   Well, I would like to thank you both for your time. And also I like to reiterate that the support I got through the GFS Grant was pretty timely, and very supportive. And I could develop that project based on that information. So I would keep looking at future opportunities from GFS folks that I can come up with and collaborate with folks from other disciplines. And I would encourage young faculty at K State to look for those opportunities. And to come up with ideas there where they can collaborate with folks like me sitting in Hays versus in you know, in Manhattan and we come to know each other. That's a great opportunity and really appreciate all the support you guys have.   So glad it worked out well. And thank you for your efforts. They're very much.   Thank you.   If you have any questions or comments you would like to share check out our website at https://www.k-state.edu/research/global-food/ and drop us an email.

Dr. Brian Jenks stops in for happy hour this week and leaves us with an incredible amount of great weed science wisdom to sit and think about. Brian's area of weed science expertise focuses on the diverse crop rotations of western North Dakota but there are all kinds of great parallels that everyone will find useful! You'll want to get a notebook ready as you'll find yourself taking notes as you make a weed control plans for next season!

November 23, 2021Herbicides, particularly those that contain glyphosate, are already in short supply due to supply chain issues plaguing the U.S. Dr. Bill Johnson, Purdue Professor of Weed Science, join Extension Soybean Specialist Shaun Casteel and Corn Specialist Dan Quinn to discuss the price hikes and availability of herbicides for this spring.They also discuss what an alternate plan might look like if glyphosate and glufosinate-based herbicides are unavailable.

One of the things we've learned over the years of doing this podcast is that we love episodes that feature both a farmer and a researcher to really capture both the complexity and the practicality of farming and soil health. That's exactly what we have today, specifically talking about barley, and the work being done to make barley a more desirable part of the rotation to build healthier soils. Anthony Thilmony is a 4th Generation farmer in the Valley City, North Dakota area. He has a masters in Weed Science and has worked in both research and sales before returning to the farm full time. Joining Anthony is Dr. Dave Franzen, a Soil Scientist with North Dakota State University in Extension. Dave and Anthony talk about the advantages of barley, why it hasn't won more acres in the past, and the research that's being done to help farmers grow more marketable barley for malting. “I think this is exciting because barley does have a fit with the soil conditions we have in this state. Especially as you go into this rolling territory where we have the variable soils. We have saltier soils and barley is a crop that is very agronomically acceptable, but we quit raising it because we got tired of the marketing side.” -Anthony Thilmony For farmers like Anthony, barley used to be a common crop before corn started taking over acreage in the area. But Dave says barley still has a lot of advantages over other crops if some of the disadvantages can be mitigated, which is what his research is all about. This win-win between capitalizing on the soil health benefits of barley while still raising a quality crop that can make grade for malting premiums could allow more farmers to have their cake and eat it too. “The overriding thing was the soil health benefits of a short season crop. And it certainly did that. We could grow a ton of dry matter or so after barley compared to a few hundred pounds in the corn and soybeans. So if you're wanting to draw down on the water in a system so that you don't get salts, you mitigate salts so that you can get in there a little bit earlier in the springtime, the barley is probably part of that.” -Dr. Dave Franzen This Week on Soil Sense: Meet Anthony Thilmony, a fourth generation North Dakota farmer, and Dr. Dave Franzen, a Soil Scientist with North Dakota State University in Extension Discover the historical context and future potential for the use of the barley in North Dakota operations Connect with Soil Sense Soil Sense Initiative Soil Sense Podcast is hosted by Tim Hammerich of the Future of Agriculture Podcast.

Wah Gwan? How you Dey? What's Good? Ahh time certainly flies when you're having fun and although we're sad to see another season come to an end, we're extremely thankful to all of our listeners, friends, family, and guests that have supported us on this Podcast Journey. With that said, seeing this will be my host episode this season, you know your Host and Humble Extrovert@G_Ransome had to arrange something super special for today's discussion. Which, if you're a fan/follower of the podcast, already know is a subject I hold very dear to my heart. That's right y'all! We're talking about that MaryJane, Bud, Sticky-Icky, Ganja, Purp, Hashish, Grass, Reefer, but specifically 1st time edible experiences, infusions, and a dab of Weed Science (cause you know we gotta keep it CULTURED!).Major thanks to this episode's guest: Charity Howard, Food Scientist and Consultant for Food and Beverage  @DopeCulinaryrxns for making this possible, and extending her expertise, and insight on the matter. So tune in Y'all, because it's finna get real!! REP' YOURs: To complement today's discussion I'd like to dedicate this episode's Rep Yours shout out to RollUpLife, Inc which is a blackowned technology-based cannabis company that offers a unique and secure delivery experience covering all transportation needs for growers, dispensaries and consumers in New Jersey. Roll-up life aims to be the premier delivery solution for both CBD and THC products within NJ and possibly all of the East Coast. I'd like to add that I've personally met both the Founder and CEO Tiyahnn Bryant and COO/Co-Founder Precious Osagie- Erese, and they have been blazing the trail on both the social equity and logistical front of the cannabis industry. As advocates for representation within the industry, through their partnerships, RollUpLife was able to raise 100K$ in funding to help minority business owners in the cannabis space.

Cannabis scientist Kim Neubauer joins James and Dave to talk about the science behind cannabis, answers listener questions, and discuss the future of weed.

Our guest is Dr. Godfrey Pearlson, director of Olin Neuropsychiatry Research Center, which is part of the Hartford HealthCare Institute of Living. Dr. Pearlson is also the author of “Weed Science: Cannabis Controversies and Challenges” which takes a deep dive into what we really know about marijuana.  They discuss the recent legalization of recreational cannabis in the state of Connecticut. What do we stand to gain, in the form of recreation and revenue – or – what do we stand to lose, in respect to potential recreational risk?The Olin Neuropsychiatry Research Center (NRC) is a clinical neuroscience research facility that was established in 2001. The Olin NRC's mission is to conduct neuroscience research of psychiatric illnesses and rapidly translate that research into new and effective treatments.Read this article featuring Dr. PearlsonIt's ‘Weed Science': Here's a Blueprint for Safe Marijuana Use

Não é por acaso que as primeiras menções a ervas daninhas remontam aos tempos bíblicos. A presença de plantas que interferem negativamente na cultura principal do produtor é um incômodo que há milênios atravanca plantações. Segundo a Empresa Brasileira de Pesquisa Agropecuária (Embrapa), o problema pode acarretar em estragos que vão desde a queda na qualidade dos produtos até as perdas substanciais na colheita. Ainda de acordo com o órgão, estima-se que os déficits ocasionados pelas ervas daninhas possam chegar a uma média de 13% a 15% da produção de grãos. Esse tipo de planta é persistente. Em boa parte, isso se deve a um potencial atípico para se desenvolver nos mais variados ambientes: dos lugares secos aos úmidos, das temperaturas baixas às elevadas e nos mais diversos tipos de solo. A expansão pelo campo tende a ser rápida e abrupta, já que elas conseguem originar sementes viáveis em abundância, sob as mais distintas formas de dispersão. Outro potencial dessas espécies é a resistência: elas são fortes e conseguem resistir bem a pragas e doenças. É exatamente pelo seu poder de sobreviver sob as mais diversas condições que as ervas daninhas se tornam grandes competidoras por luz, água e nutrientes. Quais são as plantas consideradas ervas daninhas? Segundo a Embrapa, a maioria das 350 mil espécies conhecidas são fonte de “dor de cabeça” para o produtor rural. Elas crescem sobre as culturas e comprometem a produção, mas nem todas são um problema. O órgão afirma que 3 mil delas são cultivadas como alguns tipos de capim, sendo úteis à alimentação de animais. Ainda dentro desse total de dezenas de milhares de espécies identificadas, por volta de 250 mil são universalmente consideradas plantas daninhas. Em torno de 40% delas pertencem a apenas duas famílias: Poaceae (gramíneas) e Asteraceae (compostas). Sobre este tema, vamos conversar com Guilherme Bráz, presidente da 32ª Edição do Congresso Brasileiro da Ciência das Plantas Daninhas, que acontecerá em julho do próximo ano na cidade de Rio Verde, GO. Engenheiro Agrônomo, graduado em Agronomia pela Universidade de Rio Verde. Mestre e Doutor em Agronomia, na área de Ciência das Plantas Daninhas, pela Universidade Estadual de Maringá. Realizou parte do seu Doutorado na Universidade de Flórida, em Gainesville (EUA). Atualmente, compõem o quadro de docentes da Faculdade de Agronomia da Universidade de Rio Verde, e é docente permanente no Programa de Pós-Graduação em Produção Vegetal desta instituição.

“As a psychiatry resident I wondered if cannabis does to people what catnip does to cats. That turns out to be a completely incorrect assumption.” This episode is brought to you courtesy of Trichome Institute, providers of most excellent cannabis education and certification programs. Trichome courses enable you to Weed Better! Dr. Godfrey Pearlson, the esteemed neuroscientist, researcher, and author of Weed Science talks with me about how our favorite plant works in the brain, heart (and maybe even the soul) of human beings On this episode the esteemed neuroscientist, Yale professor, and author Dr. Godfrey Pearlson, joins me to talk about what we know and don't know about the way cannabis works in our brains (and hearts, and maybe our souls, too). This episode could also be called “Cannabis: The Good, The Bad and The Mysterious and if you tune in you'll learn:The Good: Why colors seem more vibrant, why time moves more slowly, why so many musicians say they find more space between notes when using cannabis.The Bad: We explore the evidence linking cannabis to psychotic illnesses as well as the paradoxical evidence showing that ultra-high doses of CBD reduces some psychotic symptoms. We also explore the evidence between lethal car crashes in states that have legalized -- and why this is not a reason to continue the prohibition.The Mysterious: Many topics of interest here, but one of great interest to me: why so many of us need less cannabis to get high as you age.And finally, for all of you who have always wondered if cannabis does to humans what catnip does to cats, the answer is revealed within!

Episode Notes Tumbleweeds, icon of the... desert? Grasslands birthed some of the world's worst tumbleweed invaders, and there's more to them than their iconic "American old west" imagery. Desert caviar, savior of the cattle industry, and colonizer extraordinaire, this broad paraphyletic group of plants have been terrorizing and blessing the world for centuries. Nicole breaks down why tumbleweeds are pretty neat. PS keep your pet tumbleweeds on leashes. Thanks for listening to our weekly exploration of why grasslands are the best biome.

Nesse episódio eu conversei com Aldo Merotto Jr., professor do curso de Agronomia da UFRGS. Atualmente o professor Aldo Merotto é o presidente da Sociedade Brasileira da Ciência das Plantas Daninhas (SBCPD). Nós conversamos sobre a SBCPD, falamos sobre a atuação da sociedade no Brasil, sua importância e os desafios dessa entidade que congrega pesquisadores, profissionais da extensão, produtores e estudantes. Nós falamos também da nova revista Advances in Weed Science, publicada pela SBCPD. Anteriormente denominada de revista Planta Daninha, esse periódico passou por uma grande transformação para poder ser mais atrativa aos leitores e competir, nesse caso, no bom sentido, com outros periódicos da área. A alteração no nome foi apenas uma das mudanças, no sentido de aumentar a penetração da revista, e por consequência, de trabalhos realizados no Brasil e em outros locais do mundo. Você pode conhecer mais sobre a SBCPD acessando o site https://sbcpd.org/. Para conhecer o periódico Advances in Weed Science e ficar por dentro de trabalhos mais recentes na área de plantas daninhas acesse o site https://awsjournal.org/. Quer saber mais sobre a SBCPD e sobre a revista científica Advances in Weed Science, fique com a gente e ouça esse episódio do MIPD47.

Today in episode ten, we explore harvest aids with Dr. Drew Lyon from Washington State University. We also get an update on current pulse markets from Kevin Buxa of Halo Commodity Company based in Fargo, ND.  If you're new to pulse crops, they include crops such as field peas, chickpeas and lentils. This show follows some pulse crop farmers through the growing season and dives into the research that's helping them through some of the challenges they face. We'll also talk to a number of other industry stakeholders along the way.  We begin today's episode with an update on the fundamentals driving pulse markets. Kevin Buxa of Halo Commodity Company joins us. Based in Fargo, Kevin purchases commodities on-farm in North Dakota and Montana, and sells to various processors and handlers throughout the region. He also runs a stand-alone third party trucking company which enables him to expand his trading to a larger geography and more markets. For pulses, his primary focus is on peas and lentils. Then we turn our attention now to our featured topic: harvest. Pulses are fairly indeterminate, which means they will continue to flower until they reach some sort of stress, such as lack of moisture, high temperatures, or nutrient deficiency. However, harvest timing is critical to optimize yield and quality, so growers often dessicate their crops in preparation of harvest.  Here to talk about this process and the types of available harvest aids is Dr. Drew Lyon. Drew is a Professor and the Endowed Chair of Small Grains Extension and Research for Weed Science at Washington State University in Pullman. Prior to moving to Washington in 2012, he spent 22 years as a Dryland Cropping Systems Specialist at the University of Nebraska at the Panhandle Research and Extension Center in Scottsbluff. His endowment is from the WA Grain Commission, so he spends a lot of his time with wheat growers, but most of them also include pulses in their rotations. We have a lot more great information coming your way throughout the 2020 growing season. Please subscribe and tell a friend who is also interested in pulses. You can also find all of the episodes at http://www.growingpulsecrops.com (www.GrowingPulseCrops.com).  This show is brought to you by the Pulse Crops Working Group with support from the North Central IPM Center. We're releasing two of these every month throughout the growing season, so we look forward to bringing you your next episode very soon.   

On this week’s AHRI Snapshots we chat with Dr Gurjeet Gill. He’s an Associate Professor in Agronomy & Weed Science at the School of Agriculture, Food and Wine at University of Adelaide. Gurjeet, along with his colleague Ben Fleet recently completed some research that says if you don’t get a knockdown in, it’s not a problem. Delaying the sowing of wheat or barley to get a knockdown in some cases lead to a reduced number of grass weeds in crop, but the weeds in the later sown crop often set more seeds than the lower number of weeds in the early sown crop. This work was also covered in AHRI insight last week by Peter Newman - check it out here: https://ahri.uwa.edu.au/dont-delay-sowing-to-beat-ryegrass/

In the latest episode, I had a chat with Dr. Jim Brosnan, Professor at University of Tennessee at Knoxville. We discussed some of the latest things going on in the world of Weed Science and more. We also discussed the latest upcoming Digital Turfgrass Tuesdays that the UT Program is rolling out. The First Tuesday of each month from May thru November will be a webinar that anyone can tune into and hear some really great content from the educators at UT Knoxville. Information can be found here:  http://www.tennesseeturfgrassweeds.org/Pages/TurfTuesday.aspx We also got a little Football talk in about his beloved Tom Brady heading to Tampa and I think he hung up on me during our conversation as I was asking him about Tom being a Titan? You will have to see for yourself. Thanks again to Dr. Brosnon for coming on. Be sure to rate, review, share and subscribe.  Go check it out!

  Weeds are a tremendous problem in agriculture, costing farmers billions a year in crop loss and the cost of control.  In Europe one of the critical weeds is black grass, which causes great losses [...]

Dr. Al Orgeron is the LSU AgCenter weed expert. He conducts a variety of experiments with herbicides to control weed populations in Louisiana’s sugarcane fields. He reports several times a year to the farming community. The Louisiana Sugarcane News Podcast recorded Al’s January 2019 presentation at the White Castle, Iberville Parish growers meeting.

It’s been a big year for AHRI. Former AHRI Director, Stephen Powles retired from the position earlier in the year, with Professor Hugh Beckie from Canada taking on the role. We also saw the opening of the GRDC-funded Agronomy Laboratory at the University of Western Australia. Research is at the core of what we do though and we didn’t do that in halves this year either! Not only did AHRI produce significant papers, but other weed science groups nationally also made important discoveries. In this podcast, AHRI Director Hugh Beckie gives an overview of the year that was and provides some insights into what's to come for AHRI in 2019.

Back when they were young, nervous, and pressed for on-air time, Kira & Keera did an episode of Everything of Interesting about the science of cannabis and its constituent chemicals. Today they revisit the subject, armed with a lot more knowledge and far more confidence. In this episode, K+K cover the difference between Indica & Sativa, how THC and CBD affect your brain, and whether or not nature wants us to get high.

Michele Salvan, del nostro comitato scientifico, parte con una rassegna stampa delle riviste scientifiche specializzate in "erbacciologia". Fra queste c'è anche la prestigiosa Weed Science, dell'Università di Cambridge, di cui ci ha incuriosito una pubblicazione riguardante la gestione delle erbacce al 2050, abbiamo fatto a Michele qualche domanda. - Proseguiamo poi raccontandovi di un'acqua un po' particolare.
