A review of federal documents finds that the U.S. Environmental Protection Agency lessened wildlife habitat regulations after Monsanto presented research with low estimates of how far the weed killer dicamba can drift, reported the Midwest Center for Investigative Reporting. The EPA approved the use of dicamba on soybeans with confidence that dicamba would not drift to neighboring crops or wildlife habitats; however, independent studies report that dicamba drift damaged more than 3.6 million acres of soybeans in 2017, along with oak trees, wildlife habitats and vineyards.
