EPA Delays Proposed Spray Drift Rules After Farmer Backlash

Restrictions on wind speeds and nozzle heights were met with strong opposition from farmers and industry groups.

The U.S. Environmental Protection Agency (EPA) has placed its recommendations regarding herbicide-drift tolerance on hold after receiving over 5,000 letters, phone calls, and other feedback from farmers, agricultural dealers, and educators who felt the proposed spraying restrictions were unfair and unworkable.

Why it matters

The proposed EPA guidelines would have significantly limited when and how farmers could apply herbicides, which is a critical tool for controlling weeds in no-till farming systems. Farmers and industry groups argued the restrictions were not based on sound science and would have severely impacted their ability to effectively manage their crops.

The details

The EPA's proposed guidelines included limiting spraying to wind speeds under 10 mph and nozzle heights no more than 4 feet off the ground. However, studies have shown there are few days in the spring and fall when wind speeds are that low, especially in Western states. Agronomists like Bryan Young at Southern Illinois University have been researching ways to mitigate herbicide drift through droplet size and application methods, but argue the EPA's blanket restrictions went too far.

  • The EPA proposed the herbicide-drift guidelines over a year ago.
  • The agency recently placed the recommendations on hold after receiving over 5,000 comments from the agricultural community.

What they’re saying

“Without a doubt, there is more opportunity for drift to occur because of post-emergence application.”

— Bryan Young, Agronomist

“Studies have shown that there are few days in the spring and fall when wind speeds were under 10 mph in Illinois. Western states have even fewer days where wind speeds are under 10 mph.”

— Jean Trobec, Government Relations Director

What’s next

The EPA is expected to review the feedback it received and potentially revise its proposed herbicide-drift guidelines before issuing any final rules.

The takeaway

This episode highlights the ongoing tension between regulators seeking to limit environmental impacts and farmers who rely on effective herbicide application to manage weeds in their no-till operations. The EPA will need to balance these competing interests as it works to finalize any new rules around herbicide drift.
