Dacthal manufacturer provides guidance on product return after EPA’s stop-use call

The Environmental Protection Agency (EPA) issued an emergency order on Aug. 6, 2024, immediately prohibiting any application, sale, distribution or transportation of Dacthal products, except for the express purpose of returning it to the retailer it was purchased from.

“Anyone who has Dacthal (DCPA) in their possession should contact the retailer it was purchased from and coordinate the return of the product immediately as part of this recall,” said John Scott, Colorado Department of Agriculture’s Pesticides Program section chief.

The recall includes both products that have been opened and products that have been unopened. Should you have any questions, please contact your retailer or AMVAC Customer Service Team at 888-462-6822.
