Bayer Crop Science Canada Statement U.S. Court Ruling on Dicamba Registration

On February 6, 2024, the U.S. District Court in Arizona vacated the Environment Protection Agency’s (EPA) registrations for dicamba products based on procedural grounds, finding that the EPA “did not follow the FIFRA notice and comment provisions” when it issued the registrations. 

The recent court ruling in the U.S. has no impact on Canada’s use or registration of Roundup Xtend® 2 with VaporGrip® Technology herbicide and XtendiMax® 2 with VaporGrip® Technology herbicide. Bayer stands behind the safety of our products, including dicamba, which is an important herbicide for Canadian farmers. 

This ruling is a result of a procedural error and not related to the safety of the product. There are no changes to MRLs (tolerances), enabling the export of agricultural products into the U.S. 

Bayer respectfully disagrees with the ruling against the EPA’s registration decision, and we are assessing our next steps. Our U.S. team awaits direction from the EPA on important actions it may take in response to the ruling.

Corn pollination may be behind us, but the work isn't over.

In this field update from the Nutrien Innovation Farm in Champaign, Illinois, agronomist Tim Sickman discusses why growers should stay engaged with field scouting during the R3 (milk) stage of corn development. While favorable weather, strong pollination, and early grain fill are encouraging signs, important questions about crop nutrition and yield potential still remain.
