Ruling says EPA ignored clear evidence that the new herbicide would cause widespread damage to crops

The Environmental Protection Agency (EPA) broke the law in approving agricultural weedkilling products sold by Bayer and two other chemical giants, ignoring clear evidence that the new herbicides would cause widespread damage to crops, a federal court ruled on Wednesday.

The decision by the US court of appeals for the ninth circuit invalidates the registrations for dicamba-based herbicides made by Monsanto, which is owned by Bayer AG, BASF and Corteva Agrisciences that are designed to be sprayed on genetically engineered soybeans and cotton. The court order effectively makes it illegal for farmers to continue to use the dicamba herbicides this summer as they tend to millions of acres of crops. 

In a stinging rebuke, the court said it had no choice but to cancel the EPA’s approval of the herbicides because the agency had strayed so far from its duty to properly assess the dangers presented by the “new use” of dicamba.
