On Friday, public interest organizations representing farmers and conservationists made their legal case in a federal lawsuit against the U.S. Environmental Protection Agency (EPA) and the Monsanto Company, challenging EPA’s approval of Monsanto’s new “XtendiMax” pesticide. XtendiMax is Monsanto’s version of dicamba, an old and highly drift-prone weed-killer. EPA’s approval permitted XtendiMax to be sprayed for the first time on growing soybeans and cotton that Monsanto has genetically engineered (GE) to be resistant to dicamba.
The papers filed in court tell the story of how EPA should have known this would occur, yet instead was pressured by Monsanto into approving the pesticide without any measures to prevent vapor drift. The evidence in the case also shows that in late 2017, under pressure to take some action, EPA adopted revised instructions for use Monsanto proposed and approved—measures that agronomists believe will again be ineffective.
