2020 Season Updates

Bayer assessing Next Steps after Court ruling on XtendiMax Herbicide registration


On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit issued a ruling that vacates current U.S. registrations of certain low-volatility dicamba products, including XtendiMax® Herbicide. The ruling comes after a group of environmental organizations filed a petition with the Court challenging the U.S. Environmental Protection Agency’s 2018 registration decision.

We strongly disagree with the ruling and are assessing our next steps. We will also await direction from the EPA on actions it may take in response to the ruling.

We will keep this webpage updated with the latest information about the ruling and our next steps.

Depending upon actions by the EPA and whether the ruling is successfully challenged, we will work quickly to minimize any impact on our customers this season. Our top priority is making sure our customers have the support they need to have a successful season.

The ruling pertains specifically to the EPA’s 2018 registration decision, which expires in December 2020. We are currently working to obtain a new EPA registration for XtendiMax for the 2021 season and beyond – we hope to obtain the new registration by this fall.

Know that Bayer stands fully behind XtendiMax. We are proud of our role in bringing innovations like XtendiMax forward to help growers safely, successfully, and sustainably protect their crops from weeds. We will continue working with the EPA, growers, academics, and others to maintain long-term access to this important tool.

Additional Background:

In 2019, a petition was filed in the U.S. Court of Appeals for the Ninth Circuit against the EPA for its decision in 2018 to extend the registration of low-volatility dicamba products, including XtendiMax. The petition was filed by the National Family Farm Coalition, Center for Food Safety, Center for Biological Diversity, and Pesticide Action Network North America.

The petitioners requested the Court to vacate the current U.S. registrations of certain low-volatility dicamba products, including XtendiMax. The petitioners claim the EPA’s 2018 registration decision was based on insufficient evidence and therefore violated the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

In April 2020, the Court heard oral arguments on the petition. The EPA defended its science-based registration decision. While this petition was brought against the EPA, Bayer joined the case as an intervenor and helped defend the EPA’s science-based decision.

On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit issued a ruling that vacates current U.S. registrations of certain low-volatility dicamba products, including XtendiMax. The ruling comes after a group of environmental organizations filed a petition with the Court challenging the U.S. Environmental Protection Agency’s 2018 registration decision. We strongly disagree with the ruling and are assessing our next steps. We will also await direction from the EPA on actions it may take in response to the ruling.

The EPA conducted an extensive review and considered all relevant science prior to issuing the current registration for XtendiMax. In October 2018, the EPA extended the registration of XtendiMax and stated that “This action was informed by input from and extensive collaboration between EPA, state regulators, growers, academic researchers, pesticide manufacturers, and other stakeholders. EPA understands that dicamba is a valuable pest control tool for America’s growers.” The EPA’s informed science-based decision reaffirms that this tool is vital for growers and does not pose any unreasonable risks of off-target movement when used according to label directions.

XtendiMax was available to U.S. growers for the first time in the 2017 growing season. Since then, many U.S. soybean and cotton growers have added XtendiMax as one important component of their integrated weed management (IWM) programs. More than 90% of customers surveyed have reported satisfaction with the weed control XtendiMax has offered. Click here for videos of growers talking about their experience with XtendiMax.
