Chlorpyrifos, the Active Ingredient in Lorsban Peanut Notes No. 189 2021

David,

I do not know if you received this, but it probably should go out as a peanut note with an * to make sure everyone realizes this is Lorsban.

This message is for County Pesticide Coordinators and certain Extension specialists.

Please see the clarification on the timeline and implications of EPA's Chlorpyrifos tolerance revocation from James Burnette, Director of the Structural Pest Control and Pesticides Division, N.C. Department of Agriculture and Consumer Services.

To try and provide a bit more context to EPA’s recent actions concerning chlorpyrifos, as you know, on August 18, EPA announced that it was issuing a final rule to revoke the tolerances for Chlorpyrifos.

The revocations of the tolerances for all commodities will become effective 6 MONTHS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER.  To date, the final rule has not been published, so the clock has not started.

The Agency has set the expiration date for these tolerances to satisfy its international trade obligations and notice requirements.  So, any food crops already treated or which are treated in the interim could still work their way through the channels of commerce. Any products treated after the six-month date would be considered adulterated and any use on food crops after that date would be considered a misuse.

EPA also stated that it would issue a  companion Notice of Intent to Cancel ---this concerns those pesticide registrations with food uses on the labels----registrants could remove the food uses on products that contain both food and non-food uses.  The date for the Notice of Intent to Cancel has not yet been determined, but the Agency says it is “coming soon.”  EPA stated that they could see voluntary cancellation requests from registrants come in during this period, but if not, they will follow through with the Notice of Intent to Cancel.

Again, we have still not seen the federal register notice, so all of the dates are still up in the air.

NON-FOOD uses are NOT included in these actions.  These include cattle ear tags; public health uses for mosquitoes; and USDA Quarantine uses for Fire Ant management, etc.  Those uses can continue to be registered at this point.

We hope this information is useful, but don’t hesitate to let us know if we can provide additional information.

Sincerely,

Jim
