Pesticide Regulation Takes Center Stage at Commodity Classic 2023

This year’s Commodity Classic highlighted the pressing issues surrounding pesticide regulation as farmers evaluate new dicamba restrictions, Endangered Species Act (ESA) requirements, and ongoing glyphosate litigation, all of which will influence the agricultural landscape heading into 2026.

Key Discussions on Current Regulations

A panel discussion on the Successful Farming Main Stage included experts such as Tommy Butts, Extension Weed Scientist at Purdue University; Elizabeth Burns Thompson, Executive Director of the Modern Ag Alliance; and Alan Meadows, Tennessee farmer and director of the American Soybean Association. They examined the practical, legal, and on-farm implications of regulatory changes.

Dicamba Registration and Its Implications

Tommy Butts: The two-year registration for dicamba functions as a probationary period. While it remains available, federal approval will soon undergo another review, unless court interventions arise. Moreover, growers should recognize that resistance to auxin chemistries is developing. A robust weed management program is necessary, focusing on multiple modes of action to ensure effectiveness against resistant weeds.

Pesticide Label Changes

Significant label changes include a 240-foot downwind in-field buffer that excludes neighboring agricultural fields, an R1 soybean growth-stage cutoff, temperature restrictions over 95°F for spraying, and no addition of AMS in tank mixes. Potential hard calendar cutoffs may further complicate spraying days, particularly in southern regions.

The Value of Dicamba in High-Resistance Areas

Alan Meadows: In areas like West Tennessee, where resistance is a challenge, having dicamba as an option continues to be vital, even with new restrictions. Farmers must layer various chemistries to maintain effectiveness, as losing valuable tools would pose greater concerns than operating under stringent rules.

Understanding Glyphosate Litigation

Elizabeth Burns Thompson: The glyphosate litigation brings forth a crucial question: what constitutes a sufficient label? While the EPA conducts comprehensive scientific reviews, court rulings occasionally challenge this, emphasizing additional warnings not supported by science. This inconsistency creates significant liability for manufacturers, turning litigation into a multi-billion-dollar test case.

The Impact of Product Withdrawal Threats

Alan Meadows: The anxiety stemming from potential product withdrawals is palpable among farmers, who rely on these technologies for effective management. The fear of losing critical tools like dicamba or glyphosate creates ongoing challenges for agricultural productivity.

ESA Requirements and Herbicide Labels

Tommy Butts: Recent litigation has compelled the EPA to integrate Endangered Species Act (ESA) requirements into herbicide labels. While making these adjustments may appear daunting, increased documentation surrounding pesticide use limitation areas and mitigation strategies is manageable and crucial for compliance.

Responsibility for Compliance Under ESA

Tommy Butts: Responsibility for adhering to ESA compliance falls primarily on the individual applicator. Better communication among farmers, agronomists, and retailers is essential to ensure smooth navigation of the new documentation requirements.

Navigating ESA Discussions with Landowners

Tommy Butts: Open communication is key when discussing ESA requirements with landowners. While some may understand agricultural dynamics, others may not, making honest conversation essential to navigate these regulations successfully.

Focus Areas for Farmers in 2026

Tommy Butts: Staying ahead of weed management requires a solid plan, understanding resistance trends, compliance with documentation, and timely action based on weather conditions. Preparation and flexibility will be crucial as challenges arise.

The Importance of Policy Engagement

Elizabeth Burns Thompson: Farmers must advocate for their needs, clarifying misconceptions while communicating the importance of tools like glyphosate. Engagement is vital to influence policy effectively.

Final Thoughts

Alan Meadows: While agricultural practices are essential, close attention to legislative changes is equally crucial. Farmers must tell their stories to ensure their value and needs are recognized in policy discussions.

The Bottom Line

As pesticide regulations become more stringent, with ongoing litigation pressures and new documentation requirements, farmers must engage actively. Despite the complexities, access to essential tools for weed management remains vital for maintaining agricultural productivity.

“Pesticides may not seem like a sexy topic,” noted Burns-Thompson, “but the stakes for production agriculture have never been higher.”
