In 2018, EPA extended the registration for two years for over-the-top use (i.e. use on growing plants) of Dicamba to control weeds in fields for cotton and soybean plants genetically engineered to resist Dicamba. This decision was informed by extensive collaboration between EPA, the pesticide manufacturers, farmers, state regulators, and other stakeholders. The registration includes label updates that add protective measures to further minimize the potential for off-site damage. The registration will automatically expire on December 20, 2020, unless EPA further extends the registration. States affected include Iowa, Illinois, Minnesota, and Wisconsin.
