EPA Approves New Corn Pesticide Residue Limits
Published Date: 6/30/2026
Rule
Summary
The EPA just set safe limits for epyrifenacil pesticide residues on corn, soybeans, wheat, and rapeseed. Farmers, food makers, and pesticide companies need to know these new rules start June 30, 2026, with a deadline to raise any concerns by August 31, 2026. This helps keep our food safe while letting growers use this pesticide responsibly.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 0 costs, 1 mixed.
Who May Be Affected: Farms and Makers
The EPA says agricultural producers, food manufacturers, and pesticide manufacturers may be potentially affected by this rule (NAICS codes 111, 112, 311, and 32532). If you operate in those sectors, the new tolerances for epyrifenacil are relevant to your operations and product compliance.
Infant/Child Safety Factor Set to 1x
EPA determined the Food Quality Protection Act (FQPA) safety factor for infants and children should be reduced to 1x in this action. That means EPA concluded the established tolerances are protective of infants and children based on the available toxicity and exposure data.
Epyrifenacil Tolerances at 0.005 ppm
The EPA established legal limits (tolerances) of 0.005 parts per million (ppm) for epyrifenacil residues on listed commodities, including field corn (forage, grain, stover), rapeseed seed, soybean (forage, hay, seed), and wheat (forage, grain, hay, straw). These tolerances are effective June 30, 2026 and compliance is measured by the amount of epyrifenacil in or on the commodity.
Harmonization and Processing Coverage
EPA modified several tolerances to harmonize with upcoming Canadian Pest Management Regulatory Agency registrations and established that raw commodity tolerances for corn, soybean, and wheat also cover processed commodities. EPA also determined a tolerance for field corn hulls is not necessary. Several commodities (rapeseed seed; field corn grain; soybean seed; wheat grain) are set at 0.005 ppm.
