The U.S. EPA Announces New Registration for Low-Volatility Dicamba Herbicides

The new registration enables Bayer to launch Stryax™ dicamba herbicide for the 2026 season for use in dicamba tolerant soy and cotton

ST. LOUIS--(BUSINESS WIRE)--Today, the U.S. Environmental Protection Agency (EPA) announced a new federal registration for 34 states for low-volatility dicamba herbicides. This registration will enable U.S. farmers to have access to this important weed control tool in dicamba-tolerant soybeans and cotton.

“We welcome the EPA’s scientific review and registration decision for low-volatility dicamba herbicides,” said Brian Naber, president of North America & Australia/New Zealand Region, Crop Science. “Now more than ever, growers need weed control options. Growers tell us they value the flexibility that dicamba, and XtendFlex soybeans and cotton adds to their operations. This new registration will give growers another vital tool to control tough-to-control and herbicide resistant weeds.”

Bayer will launch this new registration as Stryax dicamba herbicide, a restricted use pesticide. Stryax is the ideal dicamba option to help manage glyphosate-resistant broadleaf weeds, as well as other tough to control weeds. Stryax also offers up to 14 days of soil activity on certain broadleaf weeds, helping farmers keep their fields clean. Stryax was designed as an additional herbicide option for in-crop use with XtendFlex soybeans, Roundup Ready 2 Xtend soybeans and cotton with XtendFlex technology. All applications of Stryax will require the inclusion of a qualified volatility reduction adjuvant (VRA), such as a VaporGrip^® Xtra Agent, as well as a drift reduction agent (DRA), in the tank mix.

This registration will enable the use of approved low-volatility dicamba herbicides in-crop up to 7-days pre-harvest in XtendFlex cotton, and up through R1 in XtendFlex soybeans.

“With a federal registration in hand, we’ll begin the process of seeking state approvals,” said Dr. Ty Witten, Bayer’s vice president of commercial stewardship, Crop Science. “In the coming weeks, we’ll launch applicator training opportunities, and stewardship education to help ensure that growers and applicators have the best experience possible with Stryax herbicide.”
