US EPA approves dicamba weedkiller for use on cotton and soybeans

U.S. Environmental Protection Agency proposed Wednesday approvals for products that contain the weedkiller, dicamba. Its use was stopped by a Federal Court in 2024. The agency argues it poses no significant risk to human health or the environment. Farmers of cotton and soybeans sprayed the herbicide dicamba to control tough weeds on crops genetically modified to resist it. Environmental groups have criticised the chemical for its ability to drift and harm nearby plants. In a 2024 ruling of the U.S. District Court, the EPA was found to have violated the public input procedure in the approval of three dicamba-containing products. The product registrations were subsequently revoked. Farmers were not able to spray dicamba onto crops this year as a result. In regulatory documents, the EPA announced that it had received new approval applications from Bayer AG BASF and Syngenta. Bayer, the company that sold XtendiMax dicamba herbicide, was happy to see the EPA open a period for public comments on its proposal.

Bayer stated that the low-volatility herbicide dicamba, when used in accordance with the label, could be used safely on target.

BASF has said that it will work with regulators in order to ensure that farmers are able to use dicamba. Syngenta didn't immediately respond to an inquiry for comment.

In a press release, the EPA said that despite the fact that there was no risk for human health, certain plants were at risk. The agency proposes restrictions on the amount of chemical that can be used and when to mitigate this risk.

Kyle Kunkler was the top pesticides official in the EPA Office of Chemical Safety and Pollution Prevention. He previously worked as a Lobbyist for the American Soybean Association. The American Soybean Association has supported allowing soybean farmers to spray dicamba.

The association stated that it was reviewing EPA's proposed dicamba and that dicamba was a crucial tool for farmers.
