Enlist Duo, a Corteva Agriscience herbicide that is a mixture of 2,4-D choline and glyphosate, mostly survived legal challenges in a 9th U.S. Circuit Court of Appeals opinion today that will allow its continued use.

Corteva Agriscience, a major manufacturer of the insecticide chlorpyrifos, will stop making the chemical at the end of the year.

The 9th Circuit Court of Appeals has given the Environmental Protection Agency 90 days to decide whether to allow the use of chlorpyrifos.

A San Francisco law requiring a health warning in advertisements for sweetened beverages probably violates the First Amendment, the Ninth Circuit Court of Appeals ruled Thursday.

The Environmental Protection Agency failed to take into account the risks associated with dicamba before allowing Monsanto's Xtendimax formulation of the herbicide to be used for the 2017 growing season, lawyers for environmental groups and small family farms told a federal appeals court Wednesday.
