War Against Weeds

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.

In this episode of War Against Weeds, Tommy Butts is joined by Joe Ikley (North Dakota State University) and Tom Barber (University of Arkansas) to discuss how fall-applied herbicides fit into weed management programs across very different environments. The conversation covers glyphosate-resistant Italian ryegrass, kochia, wild oat, and waterhemp, with a focus on herbicide timing, residual activity, and product selection. They also discuss research findings, farmer adoption of fall programs, and explore how cover crops, crop rotation, and weather impact herbicide performance.
