In this episode, we talk about harvest preparedness. We hear from two of WeedSmart's extension agronomists.WeedSmart southern extension agronomist, Chris Davey, discusses the different ways growers can get the crop dry enough to successfully put it through a harvester without any blockages, such as windrowing, desiccation and crop topping. WeedSmart western extension agronomist, Peter Newman, talks about optimum harvester set-up to ensure weed seeds go into the chaff cart, chaff deck or weed seed impact mill.NEWS and LINKSWebinar recording: The economics of weeds — what they cost and the benefits of managing them effectivelyWe don't often take the time to calculate what yield reduction weeds are actually responsible for, or what a well-planned rotation for weed management can make a farming business. In our latest webinar, we discussed the economic benefits of implementing an integrated weed management approach on your farm. Upcoming webinar: Biological control of grains weeds – development of novel tools and approaches for integrationDiscover the pioneering work of CSIRO researchers Dr Ben Gooden and Dr Michelle Rafter on using biocontrol agents to control crop weeds. They will discuss their work conducting exploratory surveys of biocontrol agents and host-testing with pathogens and insects. Articles1.    Windrowing barley plus HWSC in the high rainfall zone: Tim Williams (Conmurra, SA) uses the barley phase to really drive down their weed seed bank. Tim says they windrow the barley as early as possible, cutting it low to the ground. This minimises weed seed shedding, particularly in ryegrass, so they can capture the seed and process it through the impact mills at harvest.2.    Never miss an opportunity to tackle weeds: Lance Turner says herbicide resistance, particularly glyphosate resistance, was going to take them out of cropping if they didn't start using harvest weed seed control. Twenty-five years on and the Turners still have the newer chemistries ‘up their sleeve'.3.    Mills impact the weed seed bank: Bruce McLean farms at Bool Lagoon in South Australia's high rainfall zone. He says that the limited harvest hours in the region were a major deterrent when it came to implementing harvest weed seed control, but they have found that the impact mill doesn't slow them down too much, and they have the option to bypass it if necessary.4.    Can I take an integrated approach to summer fallow management? Glenn Shepherd, agronomist and director of IMAG Consulting in Dubbo, NSW, says growers have opportunities to take an integrated approach to fallow management using the WeedSmart Big 6 as a checklist.

In this week's episode, Jessica Strauss and Peter Newman catch up in person to talk about the highlights of the GRDC Crop Updates which have been taking place across the country. Peter talks about what he presented at updates, including research done by Dr Michael Walsh from University of Sydney on the efficacy of chaff lining. We also talk about research on weed seed mills and new machinery on the horizon. Pete also talks about his presentation on strip and disc systems and how they might fit into farming systems in WA. We also discuss the Weed Chipper, developed by Dr Andrew Guzzomi and Dr Carlo Peressini from UWA and researchers from University of Sydney. The Weed Chipper now has a commercial partner in Precision Agronomics Australia. This project had received funding from the Grains Research and Development Corporation and was created in response to the growing concerns about herbicide resistance and the associated difficulties with fallow weed control. Director of McFadyen Ag Consulting and Northern Panel Chair Andrew McFadyen about the effects of the Summer rain the Northern region has received. *In the podcast we chat about presentations which were stand-outs. We didn't give the full name for 'Keith' - his full name is Keith Norman and he is a UK Farm Management Specialist. We also talked about the model on HWSC Pete developed so you can calculate the cost of different HWSC options on your farm. You can download the model here: https://weedsmart.org.au/wp-content/uploads/2020/02/Estimated-Cost-of-HWSC-calculator-Mill-life-Dec19-UPDATED.xlsx

As you’re probably already aware, here at WeedSmart we’re big advocates of harvest weed seed control. However, getting this right starts with good harvester set-up. In this podcast, we catch up with one of our WeedSmart advocate farmers, Warwick Holding, about setting up your harvester correctly, with a focus on chaff decks. We also chat with Dr Peter Boutsalis from Plant Science Consulting. He gives us a rundown on how to collect weed seeds correctly for herbicide resistance testing.

In this installment of the Gopher Coffee Shop podcast, Extension educators Ryan Miller and Brad Carlson sit down with Dr. Michael Walsh, a Weed Scientist with the University of Sydney in Australia. A special thanks to goes out our colleagues at Iowa State for hosting Michael and facilitating this podcast. Michael was on-hand to talk about harvest weed seed control (HWSC) and to demonstrate combine setup for HWSC. In this podcast we spent some time talking about Australian Agriculture, herbicide resistance in weeds, and the need for alternative weed management tactics. We talked about use of chaff carts, chaff lining and tramlining, bale direct systems, and impact mills for weed management.

The theme of the podcast this week is new tools! We talk about new weed seed impact mills out of Tecfarm and also look at some new chemistry on the horizon for agriculture. Syngenta will soon be releasing a new pre-emergent herbicide called Callisto for Australian cereal growers. It has some surprisingly Australian roots, with its active ingredient stemming from the Australian bottle brush. Syngenta's Ben Parkin joins us to talk about this. BASF is also releasing several new actives. BASF Crop Solutions WA Senior Area Sales Manager Murray McCartney talks to us about Luximax, which will be available next year. We also learn about BASF’s new group H post em, Frequency and also Voraxor, which will be available in 2021. Tecfarm Director Tom Lewis talks us through the journey so far for Tecfarm in developing and testing their weed seed impact mill too. We also have a survey at the moment on HWSC that will only take you a minute to complete. You can complete it here: https://t.co/ySB4zyTOHi?amp=1 You can also access the HWSC model Peter Newman talks about in this podcast here: https://ahri.uwa.edu.au/whats-the-cost-of-hwsc-for-you/

We have a special guest co-host this week, with Planfarm Agronomist Dani Whyte joining Jessica Strauss, providing insights on farmer interviews she conducted last harvest. Dani has been working on a GRDC RCSN project, looking at harvest weed seed control practices in the Kwinana East port zone. She conducted 10 farmer interviews in total. In this podcast, we hear from three of the farmers who participated in the project. Farmers Clint Della Bosca, Stephen Dolton and Ty Kirby all share their HWSC experiences. The focus of this project is getting the weeds in the front of the header in low yielding crops. The core messages are:  - Harvest low – 10-15cm (this means paddocks need to be clean of rocks/stumps and staff need to be trained accordingly) - Coreflute attached to finger tyne reel - Knife extensions/crop lifters on the front of the harvester. Take a listen to learn more.

In this podcast, Jessica Strauss chats with then AHRI PhD Candidate Gayle Somerville about her paper “Modeling the impact of harvest weed seed control on herbicide resistance evolution”. The modelling in this paper was a component of the PhD research of AHRI PhD student Gayle Somerville, who is now a postdoc at Arhus University in Denmark. Harvest weed seed control (HWSC) is a term that describes a range of techniques to capture and destroy weed seed on standing weed plants infesting crops at the time of grain harvest. HWSC techniques have become adopted by many Australian grain growers, with AHRI research in HWSC led by Michael Walsh (now at University of Sydney). HWSC is currently being evaluated in other parts of the world. The objective of HWSC is to target weed seed at grain harvest to minimise weed seed injection into soil seedbanks and reduce weed densities over time. It's well understood that herbicide resistance evolution in weeds would be much slower if any herbicide resistant individuals were annually prevented from injecting seed back onto crop fields. There are examples of small farms where hand-weeding of weed individuals surviving herbicide treatments has greatly delayed or prevented herbicide resistance evolution. HWSC is for very large farms. In this modeling work, Gayle Somerville evaluated the value of HWSC in minimising the rate of herbicide resistance evolution. The modeling clearly showed the benefit of HWSC in minimising resistance evolution. There is a real benefit in having the diversity tactic of the non-chemical HWSC in minimising the rate of resistance evolution. HWSC reduces weed numbers over time and helps achieve greater sustainability and longevity of important herbicide resources. Music: bensound.com

Research out of the Centre for Crop and Disease Management (CCDM)has indicated that the harvest weed seed control tool (HWSC), narrow windrow burning, also help manage the damaging fungal disease sclerotinia stem rot. Kyran Brooks did his Honours in this research, with supervisors Mike Ashworth (AHRI) and Sarita Bennet (CCDM). The trials found providing temperatures were high enough and reasonably consistent (at least 350°C maintained for 10 seconds), sclerotinia was killed. An important finding was that sparse canola stubble that had not been windrowed was difficult to burn and could not achieve the temperatures required to kill sclerotinia. We also speak with research fellow Dr Chris O’Donnell from the School of Agriculture and Food Sciences at the University of Queensland. He explains how the Australian Ground Spray Calculator works. He'll be going into more detail about this at the 'Cropping and Resistance Forum' which will be held on December 6 in Dalby. You can get tickets here: www.ahri.uwa.edu.au/events If you'd like to receive a copy of the calculator before it's official launch, you can email Chris O'Donnell and request it: c.odonnell@uq.edu.au Music: bensound.com

With the help of GRDC, Planfarm recently held Harvest Weed Seed Control (#HWSC) workshops in Western Australia. All the current approaches to HWSC were discussed in detail. In this podcast, Jessica Strauss is joined by two co-hosts, Peter Newman (AHRI, WeedSmart, Planfarm) and Nick McKenna (Planfarm) where they provide an overview of the learnings from the workshops. We hear from Goomalling farmer John Even who attended one of the workshops. He talks about his approach to weed control, including his reasoning behind choosing chaff lining as his primary HWSC management tool this season. The Cropping and Resistance Forum is also coming up in Dalby on December 6. Northern Grower Alliance CEO Richard Daniel is going to be presenting at the forum on sowthistle and wild oat management. He gives an overview of the current issues facing the northern region and gives some details on what he'll be presenting at the forum. You can get all the information and tickets for the forum here.  Music: bensound.com

Not so long ago, harvest weed seed control (HWSC) was only used by a minority of early adopting grain growers. Now it has gone mainstream and pretty soon just about everyone will be doing it. This is the result from a national Australian GRDC grower survey reported in a recent scientific publication by Michael Walsh from University of Sydney. Every few years GRDC fund a large grower practices telephone survey. The most recent survey was conducted by CSIRO in 2014, and they collaborated with Michael to design the HWSC questions. The survey revealed 43% of Australian grain growers are currently practicing HWSC and this is set to rise to 82% within the next five years. Narrow windrow burning is currently the most commonly used practice by 30% of growers. Jessica Strauss speaks with Peter Newman about the paper findings. Music: bensound.com
