War Against Weeds

In this episode of the War Against Weeds podcast, Tommy and Sarah are joined by Stanley Culpepper, Bill Chism, and Elizabeth Burns Thompson to discuss how herbicide regulations, Endangered Species Act (ESA) requirements, and ongoing litigation are shaping modern agriculture. The panel examines the challenges that regulatory complexity and uncertainty create for farmers, researchers, and industry, while highlighting the significant progress made through collaboration among growers, universities, EPA, and other stakeholders. They emphasize the importance of science-based decision-making, grower engagement, effective communication, and public education, while expressing optimism about improved cooperation, expanded mitigation options, and continued efforts to protect both agricultural productivity and environmental resources.

In this episode of War Against Weeds, hosts Sarah Ganske and Alyssa Essman are joined by Purdue University weed scientist Dr. Bryan Young and Bayer Crop Science technical product lead Dr. Kati Price to discuss diflufenican (Convintro®), a new (to the US) Group 12 residual herbicide for corn and soybean production. They explore how this herbicide fits into resistance management programs, its strengths and limitations for controlling waterhemp and Palmer amaranth, and what growers can expect regarding crop response, tank-mix partners, and stewardship. The conversation also covers practical recommendations for integrating this new tool into existing weed management programs.

In this episode of War Against Weeds, Joe Ikley and Tommy Butts sit down with weed scientists Marcelo Moretti (Oregon State University) and Ryan Hill (University of California) to explore the challenge of sucker management in perennial crops such as hazelnuts, olives, prunes, and grapes. The discussion covers how suckers impact yield, fruit quality, disease management, and weed control programs, along with current strategies including chemical pruning, mechanical removal, plant growth regulators, and emerging electrical control technologies.

Marestail has been one of the most troublesome weeds in agronomic crops for more than two decades, and growers are still searching for effective ways to stay ahead of it. In this episode, Dwight Lingenfelter of Penn State joins us to discuss marestail biology, resistance, cover crops, tillage, and the management strategies that can help reduce its impact across soybean, corn, and small grain systems.
Sarah mentions a previous episode where we cover marestail research, and that episode is S1 E9 and that can be found here!

In this episode of War Against Weeds, Joe Ikley and Alyssa Essman welcome Rodrigo Werle to share key insights from eight years of multi-state research on cover crops and weed management. The discussion explores why cereal rye has emerged as the top cover crop for suppressing troublesome weeds like waterhemp and Palmer amaranth, as well as the biomass needed to maximize weed control benefits. They also cover how cover crops fit into an integrated weed management strategy alongside residual herbicides, and what new research could mean for the future of resistance management and sustainable crop production.
