9th Circuit Court bans chlorpyrifos registration and use

All registrations of the pesticide chlorpyrifos are to be canceled within 60 days under an Aug. 9 order by a three-judge panel from the U.S. Court of Appeals for the 9th Circuit.

A 2017 order by then EPA Administrator Scott Pruitt allowed continued use of the pesticide, which is widely used in agriculture and other settings to control a wide variety of insects. The order placed the chemical under a normal EPA registration and review cycle; it was not scheduled to be evaluated for environmental safety and human health until 2022.

In its ruling, the court held that the EPA had no justification for the 2017 order and that the agency cannot refuse to act based on the possibility of future contradictory evidence. The dissenting opinion was that the court had no jurisdiction in the case.
