Federal court vacates dicamba registration


A federal court in Arizona has vacated the Environmental Protection Agency’s registrations of dicamba-based weedkillers from 2020, halting its use.

The judge ruled that the EPA did not follow the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) notice and unlawfully approved dicamba for over-the-top use on dicamba-tolerant soybeans and cotton.  The products affected are Bayer’s Xtendimax, BASF’s Engenia, and Syngenta’s Tavium.

This is the second time a federal court has found that the EPA unlawfully approved dicamba.
