US EPA Finalizes Pesticide Residue Tolerance Updates for Food and Agricultural Commodities

Details of the Update

The final rule amends pesticide residue tolerances and implements outcomes from registration review decisions conducted under the Federal Food, Drug, and Cosmetic Act (FFDCA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The EPA finalized revised tolerance levels for the active ingredients diphenylamine, diflubenzuron, flutolanil, isoxaflutole, famoxadone, aminopyralid, fenazaquin, and tembotrione following its comprehensive risk assessment.

The updated tolerances apply across a wide range of commodities, including apples, pears, cottonseed products, mushrooms, peanuts, potatoes, rice grain and by-products, soybeans and soybean by-products, brassica vegetables, citrus fruits, oats, barley, wheat, corn, tea, tomatoes, onions, spinach, artichokes, caneberries, grapes, and hops. Where existing tolerances are lowered or revoked, the EPA has introduced a six-month transition period from the publication date to support export adaptation in line with World Trade Organization requirements. 

The rule also confirms that no significant economic impact on small entities was identified and that enforcement methodologies are available to monitor compliance with the revised limits. In setting the new tolerances, the EPA gave special consideration to risks for infants and children, consistent with statutory safety requirements.

Effective Date

The final rule is effective as of February 20, 2026, the date of publication. From this date, the revised pesticide residue tolerances apply, with a six-month transition period for tolerances that are lowered or revoked to support compliance and export adaptation.

Feedback Deadline

Objections or requests for a hearing must be submitted by April 21, 2026, in accordance with the procedures set by the Environmental Protection Agency.

Why It Matters
