LITTLE ROCK, AR –The Arkansas Department of Agriculture is reminding pesticide applicators and agricultural producers of important restrictions regarding the use of dicamba products during the 2026 growing season.
In February 2026, the Environmental Protection Agency (EPA) issued new federal registrations for over‑the‑top (OTT) dicamba products for the next two growing seasons, accompanied by strengthened national restrictions. As part of this action, EPA removed all federal cutoff dates for OTT dicamba applications on soybeans and cotton. Arkansas’s state cutoff date of June 30 remains in effect.
From April 16 through June 30, the application of registered in-crop dicamba products is allowed only under the following conditions:
- One mile buffer in all directions from university or USDA research stations
- 1/2-mile buffer in all directions from certified crops and specialty crops (comprised of at least 1,000 plants or a value of over $25,000)
- 1/4-mile buffer in all directions from non-dicamba tolerant crops
- Glyphosate tank mixes are prohibited
Producers and applicators who fail to comply with federal and/or state laws and rules may be subject to civil penalties of up to $25,000 per violation, as well as possible suspension or revocation of their applicator license.
Additional information on dicamba use in Arkansas can be found on the Department’s website here.
