🌱EPA Updates Chlorpyrifos Cancellation Order for Asparagus Use
On June 24, 2024, the Environmental Protection Agency (EPA or the Agency) issued a final cancellation order pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) terminating several food uses on registered chlorpyrifos products, the majority of which were voluntarily requested by Gharda Chemicals International, Inc. (Gharda) and accepted by the Agency. Upon further review of that order, EPA identified an error, which it is correcting in this document.

No. 93182-7, as Gharda did not request termination of that use.
