SALEM, Ore. — Because of recent federal actions, do not use chlorpyrifos on any food or feed commodities after Feb. 27, 2022. There are some exceptions regarding non-bearing fruit and nut trees and cattle ear tags. For details on exceptions see EPA’s final rule.
Details: In August 2021, the U.S Environmental Protection Agency (EPA) issued a final rule revoking all tolerances on food and feed commodities for the insecticide chlorpyrifos. The final rule became effective October 2021, and all tolerances for all commodities expired and were revoked on February 28, 2022. Some common trade names of products containing chlorpyrifos are: Lorsban, Dursban, Warhawk, Pyrofos, Hatchet and Yuma. If you are uncertain whether your product contains chlorpyrifos, please review the Active Ingredient statement on the first page of the label.
EPA has issued letters to the registrants of chlorpyrifos for products with registered food uses requesting registrants act to cancel these uses. For registrations not voluntarily cancelled, EPA intends to issue a Notice of Intent to Cancel to cancel registered food uses of chlorpyrifos associated with the revoked tolerances. It is an atypical situation in which the tolerances are revoked prior to the food and feed uses being canceled. Thus even if your current label has food or feed crops on the label; it cannot be used on those crops as there is no longer a tolerance.
The tolerance revocations do not impact chlorpyrifos use on nonfood or nonfeed crops, including the uses provided on the Oregon’s SLN or 24(c) registrations. However, EPA may take action on nonfood/nonfeed uses in the future. Do not stock up on chlorpyrifos-containing products.
EPA’s federal actions supersede ODA’s rule regarding use on food or feed commodities. All other restrictions in Oregon’s chlorpyrifos rule are still in effect, you can just no longer use chlorpyrifos on food or feed commodities due to the federal action. See Oregon’s rule for more information.
Waste Pesticide Collection Events: The Pesticide Stewardship Partnership (PSP) Program currently has four Waste Pesticide Collection Events scheduled. There may be additional events scheduled in the future. For more information, go to the Pesticide Stewardship Partnership webpage (see list toward bottom of page).
Important: EPA may take additional action regarding product cancellations, sales and distribution, but the details are unknown at this time. ODA’s and EPA’s webpages will be updated periodically.
