Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Finalized Pesticide Tolerance Changes
You are an agricultural producer, food manufacturer, or pesticide company if you use or make pesticides like hydrogen cyanide, 1-naphthaleneacetic acid, carboxin, ethofumesate, thiobencarb, or propylene oxide. The EPA finalized new or revised residue tolerances for these active ingredients that take effect April 22, 2026, and list specific parts-per-million limits for affected commodities you grow or process.
Food Safety Protected by Tolerances
You as a food consumer benefit because EPA set legal residue limits (tolerances) to help keep food safe from residues of pesticides such as hydrogen cyanide and propylene oxide. These tolerances are final on April 22, 2026 and specify parts-per-million limits for many commodities to guide safe levels in food.
Ethofumesate Tolerance Expiration Extended
EPA changed the expiration date for a specific ethofumesate tolerance (for 'Beet, sugar, tops') from December 8, 2025 to October 19, 2026. This gives producers and exporters extra time to adapt to the lowered or revoked tolerance level before that particular tolerance expires.
EPA Finds No Significant Small-Business Impact
EPA certified under the Regulatory Flexibility Act that this final rule will not have a significant economic impact on a substantial number of small entities. The Agency states this action has no net burden on small entities subject to the rulemaking.
