In August of 2021, the EPA announced it would revoke all tolerances for food uses of chlorpyrifos. The final rule became effective in October of 2021 and the tolerances for all commodities expired at the end of February 2022. Corteva Agriscience and ADAMA have established a return and credit program. North Dakota Agriculture Commissioner Doug Goehring is pleased with these two companies for taking this action. “However, I’m disappointed that other registrants have not taken the same responsibility.”
