The Four-State Dairy Nutrition & Management Conference webinar series continues on Tuesday, February 3, at 12 noon CST with Dr. Wess Everman discussing the framework for the new Herbicide Strategy and how it will impact farmers and applicators will be discussed during this webinar
The EPA's Final Herbicide Strategy, aimed at protecting over 900 endangered species, will significantly alter dairy operations by introducing stricter, mandatory, and more complex pesticide application regulations. For dairy farms, which often rely on both crop production (for feed) and pasture management, this strategy means a shift toward more restrictive weed control measures.
In 2024, the EPA released the Herbicide Strategy to bring all herbicides in compliance with ESA directives. As new herbicides are labeled or current products are reviewed, changes will be made to include erosion/runoff mitigation practices and drift mitigation. The framework for these changes and how they will impact farmers and applicators will be discussed during this webinar.
Dr. Wess Everman, Assistant Professor and Extension Weed Scientist Specialist came to Iowa State University by way of North Carolina State University where he spent the last 13 years as professor and extension weed specialist. There he conducted research and extension activities, finding economical solutions to the growing problem of herbicide resistance in weeds.
