On July 22, the U.S. Circuit Court of Appeals for the Ninth Circuit denied plaintiffs’ requests in two cases to remove EPA approval for Enlist Duo, Corteva Agriscience’s weed-control product that combines 2,4-D with glyphosate.

Enlist Duo has EPA registration in 34 states, including Georgia.

A group of organizations led by the National Family Farm Coalition, filed the suit seeking a reversal of the Enlist Duo registration issued by the EPA in 2017, arguing that the agency failed to follow required procedures outline in the Federal Insecticide, Fungicide & Rodenticide Act (FIFRA) and the Endangered Species Act (ESA).

The court found that the EPA did not adequately address Enlist Duo’s risk to monarch butterflies under rules in the ESA but allowed the herbicide’s registration to remain in force while the agency works to remedy its oversight.

The three-judge panel also ruled that the EPA used appropriate procedures in issuing the registration under FIFRA.
