Cotton Specialists Corner

Entomologists Drs. Ray Frisbie (Texas A&M), Ron Smith (Auburn University), Phillip Roberts (University of Georgia), and agronomist Dr. Steve Brown (Auburn University) join host Camp Hand (University of Georgia) to discuss the history and importance of the boll weevil (Anthonomus grandis) and its eradication. Discussions surround the boll weevil and its management prior to eradication, controversy surrounding eradication during the early days, changes in cotton growth and management following eradication, and update on current boll weevil eradication efforts in South Texas and Northern Mexico. 

Extension Cotton Specialists Drs. Ken Lege (Texas A&M Agrilife), Tyson Raper (University of Tennssee), and Mike Jones (Clemson University) join host Camp Hand (University of Georgia) to discuss ways that growers across the cotton belt are adjusting production strategies with the difficult economic situation facing the farm in 2025. Conversations revolve around reducing current inputs (seeding rates, fertility) or changing production strategies entirely (ELS/conventional cotton) and associated challenges with that decision. 

Drs. Keith Edmisten and Camp Hand, cotton specialists at North Carolina State University and the University of Georgia, respectively, join host Dr. Steve Brown to discuss the economic situation facing agricultural producers throughout the US, along with the impacts of hurricanes on cotton production, specifically discussing the devastation caused by Hurricane Helene in late September. 

Byron Cole, Deputy Director of the Grading Division, and Greg Townsend, Area Director of the Visalia Cotton Classing Office, join host Steve Brown to discuss the USDA Cotton Classing System, including Some of the history behind the SystemThe processes and diligence of delivering consistent, repeatable analysis of samples within and across Classing OfficesThe actual how-to's of classing HVI versus the old wayYear-to-year challenges and efficiencies  Extraneous MatterDifferences between upland and Pima classificationPossible future improvements

Dr. Wes Porter, Extension Ag Engineer at the University of Georgia, joins host Steve Brown to talk about the JD roll picker, with a few thoughts about the comparable stripper version. We discuss a little history about the concept and talk about advancements in capabilities of these remarkable machines. We specifically address how to calibrate the module handling system and the possible uses of the resulting data.

Extension Cotton Specialists Drs. Randy Norton (University of Arizona), Brian Pieralisi (Mississippi State) and Camp Hand (University of Georgia) join host Steve Brown to discuss approaches, means, methods and challenges of irrigation in their respective regions. We also discuss WHEN to quit, when to shut off irrigation and the associated factors that go into that decision.

Cotton Entomologists Drs. Scott Graham (Auburn University) and Phillip Roberts (University of Georgia) join host Steve Brown to discuss management of this common pest ... at least a pest that is ever-present in the Southeast and perhaps some other parts of the Belt. Topics include why stink bugs are a threat in many areas, basic biology and life cycle characteristics, damage symptoms, scouting methods and thresholds as well as the intersection and influences of plant bug management with stink bugs.

Soil Scientists / Fertility Experts Drs. Hunter Frame (Virginia Tech), Glen Harris (University of Georgia), Audrey Gamble (Auburn University) and Katie Lewis (Texas A&M) join host Steve Brown of Auburn to discuss the challenges associated with K management in cotton. Sometimes, particularly in the the Lower Southeast, we can fertilize appropriately and still encounter K deficiencies, presumably because pre-bloom heat/moisture stresses limit K uptake; then during boll-fill, K demand from leaf and stem tissues can quickly  deplete plant reserves. The results can be premature defoliation, secondary fungal leaf diseases such as Stemphylium and reduced yields.

Numerous Extension Cotton Specialists from across the U.S. provide an update on the 2024 crop as of June 7.  Reports include planting progress, expected final acreage crop, crop condition and emerging issues and challenges. Information from 10 states is provided, from Arizona to Virginia.

Bhupinder Farmaha (Clemson University), Tyson Raper (University of Tennessee), John Arnall (Oklahoma State) and Katie Lewis (Texas A&M) join host Steve Brown to discuss N management in cotton. The session addresses:  Are we using too much N in some areas? Why do many N studies across the Belt show limited or even no response to N? If that is the case, where does the N come from? How much N is actually required to make a bale of cotton (and the associated seed, etc.)? Can we mine residual N in subsoil layers? Might it be possible to impose targeted nutrient stress on cotton and improve root growth and yield? And a lot more. There are clear differences in how we manage N across the U.S. It is a lively discussion on a key topic.

Drs. Brian Pieralisi (Mississippi State) and Brian Arnall (Oklahoma State) join host Steve Brown in a broad discussion on the subject of new Biological, Microbial and other products targeted to improve crop productivity. We discuss the 2023 Beltwide Cotton Incorporated project in this realm and also chase several "rabbits," including topics such as N rates (are we using too much?), soil health and "regenerative" ag.
