US EPA Proposes Dicamba Comeback for Cotton and Soybean Farmers Despite Controversy

The U.S. Environmental Protection Agency (EPA) has proposed reinstating approvals for three dicamba-based weedkillers used on genetically modified cotton and soybean crops. This move follows a 2024 federal court ruling that vacated prior registrations over the EPA’s failure to follow public input procedures, leaving farmers unable to use dicamba this season. Dicamba, an herbicide known for controlling stubborn weeds, has drawn criticism from environmental groups for its tendency to drift and damage nearby crops. Despite this, the EPA's recent review concluded that the chemical poses no significant human health risks. However, some environmental risks to plants were identified, prompting proposed application limits and usage restrictions. Major agrochemical companies Bayer, BASF, and Syngenta have applied for renewed registrations. Bayer, the maker of XtendiMax, welcomed the public comment period and defended dicamba’s safety when used as directed. BASF committed to working with regulators, while Syngenta has yet to respond. The American Soybean Association—closely linked to EPA official Kyle Kunkler, a former lobbyist—has expressed cautious support, calling dicamba a vital tool for growers. As debate resumes, the proposal reignites tensions between agricultural needs and environmental safeguards.
