The reason behind this widespread crop damage is that while Monsanto’s genetically modified (GMO) crops can withstand sprays of dicamba, other crops cannot. The seed company decided to sell its new dicamba-tolerant seeds to farmers before gaining federal approval for the herbicide specifically designed to go with the seeds—DuPont FeXapan herbicide plus VaporGrip Technology—which is supposed to reduce dicamba’s volatility and drift damage.
While Monsanto has warned farmers not to do so, farmers are illegally spraying their GMO soybeans and cotton with older formulas of dicamba to beat back weeds. Dicamba’s over-the-top usage for the growing of cotton or soybean plants has not been approved by the EPA. Any farmer who sprays this herbicide over their dicamba-tolerant crops are breaking the law and can face fines of $1,000.
