The Wisconsin Soybean Association (WSA) has joined the American Soybean Association (ASA) and fellow state soybean organizations in urging the U.S. Environmental Protection Agency (EPA) to finalize a new federal registration for over-the-top (OTT) dicamba use on dicamba-tolerant soybeans before the end of 2025. The unified request was outlined in a letter to be delivered to EPA Administrator Lee Zeldin.
In the letter, ASA, which represents nearly 500,000 U.S. soybean growers, emphasized the importance of dicamba as a critical weed-management tool, especially for controlling herbicide-resistant weed populations. The associations commended EPA for making progress on pesticide reviews and for providing growers the opportunity to offer feedback during the public comment period that closed in September.
“Our farmers need a variety of tools to effectively produce a crop each season,” said WSA Executive Director Adam Kask. “It’s important to support the ones we have.”
With the 2026 growing season approaching, the organizations stressed that growers are preparing seed and crop protection plans now. Delayed clarity on dicamba availability, they noted, puts farmers at a disadvantage during one of the most consequential decision-making periods of the year. The letter also highlighted that registrants need sufficient time to produce and distribute updated product labels before planting begins — a key reason ASA and its state partners are asking EPA to finalize the new low-volatility dicamba registration by December 31.
