The Center for Food Safety and three other environmental groups have revised their ongoing dicamba lawsuit against the EPA and Bayer CropScience. Environmental groups are challenging EPA’s amended dicamba registrations for Iowa and Minnesota. In a statement, Center for Food Safety Staff Attorney Meredith Stevenson said EPA’s actions fail to address drift damage. The groups want the herbicide off the market. Dicamba herbicides are undergoing a re-registration review. The Minnesota Department of Agriculture said it will review the draft risk assessment when it is are released by EPA.
