NASHVILLE, Tenn. (RFD-TV) — The Environmental Protection Agency (EPA) is shifting its approach to over-the-top (OTT) dicamba applications on dicamba-tolerant cotton and soybeans. Instead of calendar-based cutoffs, the agency has proposed a new system tied to temperature forecasts, requiring applicators to use data from the National Weather Service or NOAA.
The new labels move away from past state-imposed cutoff dates and instead rely on daily and next-day temperatures, according to Nicholas Brown with the North Carolina State Extension Service.
- Applications are permitted when both forecasts remain below 75 degrees Fahrenheit, with 20 fluid ounces of volatility reducing agent (VRA) required.
- Between 75-85 degrees, the VRA requirement doubles.
- At 85–95 degrees, applicators must either reduce treated acreage by 40 percent or eliminate tank mix partners, still including a VRA.
- Any forecast of 95 degrees or higher prohibits use altogether.
The EPA says the changes simplify compliance compared to the past 40-page labels, though state regulators caution that shifting from date cutoffs may complicate planning. If finalized, the new labels could apply for the 2026 growing season.
Tony’s Farm-Level Takeaway: Farmers will need to closely monitor forecasts, as temperature cutoffs replace fixed spray dates. Planning flexibility may be reduced during hot spells, making compliance more weather-dependent.
In a statement provided to RFD-TV News, a USDA spokesperson reiterated President Trump and the USDA’s commitment to farmers in difficult economic times.
