NASHVILLE, TENN. (RFD NEWS) — As farmers prepare for over-the-top dicamba applications this season, new federal safeguards are adding additional requirements and scrutiny. With updated registrations now in place, growers are being urged to pay close attention to record-keeping, weather conditions, and compliance measures.

Roger McEowen joined us on Tuesday’s Market Day Report to break down the latest changes and their implications for producers. He explained that the updated registrations include stricter application guidelines and enhanced oversight, reflecting ongoing regulatory concerns.

One of the primary issues remains drift, which the Environmental Protection Agency (EPA) continues to monitor closely. McEowen said new safeguards are aimed at reducing off-target movement, including tighter application windows, buffer requirements, and increased attention to weather conditions such as wind speed and temperature inversions.

A key new component this season is the implementation of a conservation point system. McEowen explained that growers must now adopt specific conservation practices to mitigate runoff and protect surrounding ecosystems. These measures could include field buffers, cover crops, or other approved practices that contribute to an overall environmental compliance score.

With these changes in place, McEowen emphasized that farmers will need to be especially diligent this season—keeping detailed records, monitoring forecasts, and staying updated on regulatory guidance. The EPA has indicated it will be closely watching application activity over the next two growing seasons, particularly for reports of off-target damage.

Looking ahead, McEowen said continued oversight and potential legal challenges could shape the future of dicamba use, making it critical for producers to remain informed and adaptable.

Finally, McEowen reflected on the passing of Orion Samuelson, a legendary farm broadcaster who left a lasting impact on agriculture.
