Update - Federal court vacates labels for over-the-top dicamba herbicides

On February 6, 2024, the US District Court in Arizona issued a ruling that vacated the labels for XtendiMax, Engenia, and Tavium. The court found that the EPA violated the FIFRA notice and comment mandates for issuing new-use pesticide registrations when they issued unconditional labels for the products in 2020.

On February 14, the EPA issued a cancellation order allowing the sale and use of products already in the distribution system. Products intended for use should be sold by May 31 for soybeans or June 30 for cotton. The application cutoff dates remain the same - June 30 for soybeans and July 30 for cotton.
