US court bans three weedkillers and finds EPA broke law in approval process

Ruling, specific to three dicamba-based weedkillers, is major blow to Bayer, BASF and Syngenta

Dealing a blow to three of the world's biggest agrochemical companies, a US court this week banned three weedkillers widely used in American agriculture, finding that the Environmental Protection Agency (EPA) broke the law in allowing them to be on the market.

The ruling is specific to three dicamba-based weedkillers manufactured by Bayer, BASF and Syngenta, which have been blamed for millions of acres of crop damage and harm to endangered species and natural areas across the midwest and south.
