The U.S. Environmental Protection Agency (EPA) has provided an update on the use of the insecticide chlorpyrifos, commonly known by its tradename Lorsban, for vegetable crops in 2024. Chlorpyrifos had been a crucial tool for various vegetable crops, including brassica root crops, leafy brassicas, asparagus, and onions. In 2022, the use of chlorpyrifos was canceled, but a recent development in February 2024 has reinstated all tolerances for the insecticide.
The reinstatement follows a December 2023 court ruling, and as a result, growers of crops listed on the label in previous years can now apply chlorpyrifos in accordance with label directions without any violation. Growers who have existing stocks of chlorpyrifos are allowed to use them following the label guidelines. Additionally, retailers, distributors, and suppliers are permitted to sell currently registered products containing chlorpyrifos.
It's noted that several manufacturers voluntarily canceled their registration to produce chlorpyrifos. As a result, new products will only be available through specific companies, including Gharda, Drexel, or Loveland.
This reinstatement of tolerances is expected to be temporary, and a final decision is anticipated within the next year or two. Given the ongoing concerns and issues surrounding the use of chlorpyrifos, the situation may evolve beyond this timeline.
