Cotton and soybean farmers who use dicamba to control weeds will have to follow a few new restrictions in the coming crop year.

Friday, the Environmental Protection Agency (EPA) announced an agreement with BASF, DowDuPont and Monsanto to voluntarily add additional requirements for “over the top” use on dicamba product labels.

The restrictions, according to EPA Administrator Scott Pruitt, allow farmers to use dicamba, while also minimizing the potential for drift damage to nearby crops.

“(These) actions are the result of intensive, collaborative efforts, working side-by-side with the states and university scientists from across the nation who have first-hand knowledge of the problem and workable solutions,” Pruitt said. “Our collective efforts with our state partners ensure we are relying on the best, on-the-ground information.”

Additional requirements for dicamba use on growing plants now include:

1. Classifying products as “restricted use,” permitting only certified applicators with special training and those under their supervision, to apply them; dicamba specific training for all certified applicators to reinforce proper use

2. Requiring farmers to maintain specific records regarding the use of these products to improve compliance with label restrictions

3. Limiting applications to when maximum wind speeds are below 10 mph (from 15 mph) to reduce potential spray drift

4. Reducing the times during the day when applications can occur

5. Including tank clean-out language to prevent cross contamination

6. Enhancing susceptible crop language and record keeping with sensitive crop registries to increase awareness of risk to especially sensitive crops nearby.

To arrive at the above restrictions, EPA worked with states, land grant universities and pesticide manufacturers. BASF, DowDuPont and Monsanto have reportedly agreed to make the necessary changes to products labels in time for the 2018 crop season.

“Based on the science behind our low-volatility dicamba product and learnings from the 2017 season, we are confident the required training and record keeping can address the main causes of off-target movement,” Monsanto’s Global Regulatory Lead Ty Vaughn said. “We want to stress how important it is that farmers use products approved by the EPA for use over the top of dicamba-tolerant crops, and use them in accordance with all label requirements.”

According to the EPA, it will continue to monitor these changes to “help inform our decision whether to allow the continued ‘over the top’ use of dicamba beyond the 2018 growing season.”

In late September, the Arkansas Plant Board moved to effectively ban dicamba use in the 2018 crop year due to complaints of alleged misuse and damage.

Similar complaints of alleged damage were reported in Missouri and Tennessee.

Dicamba is a broad spectrum herbicide.

Monsanto, BASF and DowDuPont are among agricultural manufacturers who use the herbicide in their products like Diablo, Banvel and Vanquish.

It’s also common in commercial and personal weed control products.Farmers and at-home users are encouraged to read and follow label directions when applying any herbicide or pesticide.
