EPA Sets New Limits for Bayer's Diflufenican Pesticide

## Summary

The EPA just set new legal limits for diflufenican pesticide residues on several foods, thanks to a request from Bayer CropScience. This affects farmers, food makers, and pesticide producers starting June 30, 2026. If anyone wants to challenge these rules, they have until August 31, 2026, to speak up—no extra costs or delays expected!

## Abstract

This regulation establishes tolerances for residues of diflufenican (CASRN 83164-33-4) in or on multiple commodities which are identified and discussed later in this document. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), Bayer CropScience submitted a petition to EPA requesting that EPA establish a maximum permissible level for residues of this pesticide in or on the identified commodities.

## Effects PRIA read

- Legal residue limits set for diflufenican: mixed, medium. The EPA established legal tolerances for diflufenican residues effective June 30, 2026. The rule lists specific limits: corn forage, grain, and stover at 0.01 ppm; soybean forage at 0.01 ppm; soybean hay at 0.015 ppm; and soybean seed at 0.01 ppm. The document names potentially affected entities as…
- EPA finds tolerances safe for public and children: benefit, low. EPA concluded there is a "reasonable certainty that no harm will result" to the general population and to infants and children from aggregate exposure to diflufenican residues. EPA reduced the FQPA safety factor to 1X based on its review of toxicity and exposure data.
- EPA set more conservative soybean tolerances: mixed, low. EPA revised the petitioned-for soybean tolerances to more conservative values when using the OECD calculator. The petitioner requested soybean forage at 0.015 ppm and soybean hay at 0.02 ppm; EPA finalized soybean forage at 0.01 ppm and soybean hay at 0.015 ppm. FFDCA allows EPA to finalize toleran…
- No residential uses proposed for diflufenican: benefit, low. EPA states that diflufenican is not proposed for any use patterns that would result in direct applications in residential areas. That means the rule does not authorize household uses such as lawn, garden, indoor pest control, or flea and tick products for pets.
