S10 E14 - Looking to the Future
War Against Weeds
On our last episode of season 10, all three hosts have a discussion on the future of weed science with Dr. Larry Steckel (University of Tennessee) and Dr. Aaron Hager (University of Illinois). They reflect on the evolution of weed management, including the increase of specific weed species, and the challenges of herbicide resistance. Both emphasize the need for integrated approaches, including cover crops, precision technology, and cultural practices.

S10 E13 - Weather and Weed Science
War Against Weeds
Joe Ikley and Sarah Lancaster discuss the North Dakota Agricultural Weather Network (NDAWN) and the Kansas Mesonet with directors Daryl Ritchison and Chip Redmond, respectively. NDAWN, with over 250 stations, provides high-resolution weather data, including soil moisture and temperature measurements. Kansas Mesonet, with 94 stations, focuses on real-time data for agricultural and emergency management purposes. Both networks emphasize the importance of accurate weather data for herbicide application, particularly wind speed, inversions, and delta T measurements. The conversation highlights the...

S10 E12 - Dryland Agriculture Weed Management
War Against Weeds
Sarah and Alyssa sit down with dryland experts Jeanne Faulk Jones (Kansas State University) and Dr. Drew Lyon (Washington State University). They highlight the challenges of managing weeds in semi-arid regions, including key weeds like Palmer amaranth, Kochia, and perennial grasses. They also discuss various strategies for water conservation and weed management. Smallgrains.wsu.edu Facebook page: K state sunflower district agronomy X: cropswithgenie

S10 E8 - Herbicide Premixtures
War Against Weeds
Joe & Sarah sit down with Scott Cully and Dean Grossnickle to discuss herbicide premixtures. Scott, a senior field research biology expert, highlights his role in developing products like Acuron and Storen. Dean, a technical development lead, explains his commercial perspective. They detail the development process, including formulation challenges and the importance of proper adjuvant selection. They emphasize the need for accurate application to avoid issues and the benefits of pre-mixtures for ease of use and consistent results.

S10 E7 - The HERMON Project
War Against Weeds
Sarah & Joe sit down with Dr. Eric Patterson from Michigan State University to chat about the The HERMON (Herbicide Resistance Monitoring Network) project. This project aims to create a network of researchers to develop and share new resistance tests and management strategies. The project includes 10 states and focuses on key herbicides like glyphosate, PPO inhibitors, and dicamba.

S10 E6 - Cytochrome P450s with Dr. Todd Gaines
War Against Weeds
This week Sarah and Alyssa chat with Dr. Todd Gaines from Colorado State University. They discuss the role of cytochrome P450 enzymes in herbicide metabolism and resistance. Dr. Gaines mentions ongoing research to understand the regulation of these enzymes and the potential for using gene editing to combat resistance. They also touched on the impact of stress on P450 activity and the development of new herbicides.
