Bayer’s Stryax® Low-Volatility Dicamba Herbicide Gains EPA Approval Across 34 States
12 February 2026, St. Louis: The U.S. Environmental Protection Agency has announced a new federal registration covering 34 states for low-volatility dicamba herbicides, expanding access to this weed-management option for U.S. farmers growing dicamba-tolerant soybeans and cotton.
The decision follows the EPA’s scientific review and is expected to provide growers with added flexibility at a time when pressure from hard-to-control and herbicide-resistant weeds continues to intensify. According to industry feedback, dicamba remains a valued tool—particularly when paired with XtendFlex® soybean and cotton systems—for integrated weed management programs.
Commenting on the development, Brian Naber, President for North America & Australia/New Zealand, Crop Science at Bayer, said the registration strengthens the weed-control toolbox available to growers and supports operational flexibility across diverse farming systems.
Under the new approval, Bayer will commercialize the product as Stryax® dicamba herbicide, classified as a restricted-use pesticide. Stryax is positioned to help manage glyphosate-resistant broadleaf weeds and other difficult species, while also offering up to 14 days of soil activity on certain broadleaf weeds to support early-season field cleanliness.
Stryax is designed for in-crop use with XtendFlex® soybeans, Roundup Ready 2 Xtend® soybeans, and XtendFlex® cotton. All applications will require the inclusion of an approved volatility reduction adjuvant (VRA)—such as VaporGrip® Xtra Agent—along with a drift reduction agent (DRA) in the tank mix, reinforcing stewardship and off-target mitigation.
The registration allows the use of approved low-volatility dicamba herbicides up to seven days pre-harvest in XtendFlex cotton, and through the R1 growth stage in XtendFlex soybeans.
“With a federal registration in hand, we’ll begin the process of seeking state approvals,” said Dr. Ty Witten, Vice President of Commercial Stewardship, Crop Science at Bayer. “In the coming weeks, we will roll out applicator training and stewardship education to help ensure growers and applicators have the best possible experience with Stryax herbicide.”
