EPA to ban the use of chlorpyrifos on food crops

The EPA dealt the fatal blow to agricultural uses of the insecticide chlorpyrifos on Wednesday, August 18, in a long-awaited victory for environmental, labor and public health groups who have been lobbying against the chemical for decades .

“In a final rule released today, the EPA revokes all ‘tolerances’ for chlorpyrifos, which set an amount of the pesticide allowed on foods,” the agency said in a press release. “In addition, the agency will issue a notice of intent to rescind under the Federal Insecticides, Fungicides and Rodenticides Act to revoke the registered food uses of chlorpyrifos associated with the revoked tolerances.”

The press release quoted EPA administrator Michael Regan as saying, “Ending the use of chlorpyrifos on foods will help ensure that children, farm workers and all people are protected from the potential consequences. dangerous effects of this pesticide. “

The use of chlorpyrifos (Lorsban) in agriculture has already declined significantly over the past decade, especially after its main holder, Corteva Agriscience, ceased production in 2020. But this action effectively ends all agricultural uses of chlorpyrifos on food and feed crops, including generics. . This does not immediately affect non-food uses of chlorpyrifos, such as mosquito control, which will be investigated later in 2022, the EPA noted.

“After considering the public comments, the agency will proceed to review the registration of other non-food uses of chlorpyrifos by issuing an interim decision, which may consider additional measures to reduce risks to human health and l ‘environment,’ the press release reads.

Chlorpyrifos, better known to farmers as the older product Lorsban, is an insecticide that targets stinging and sucking insects such as aphids and is mainly used in crops of soybeans, corn, wheat, cotton and cotton. orchard. Although this has been a popular pest control option in the past, its use has grown from £ 13million per year in the late 1990s to £ 5-7million per year by 2010, according to the US Geological Survey.

In February 2020, citing this drop in demand, the production of Lorsban was stopped by Corteva. At the time, the Trump-led EPA committed to continuing to re-register the chemical, which would allow generic versions to remain on the market indefinitely. (See more here :). And in December 2020, he did so, issuing a proposed interim registration decision keeping it in the market, with some label tweaks.
