Updates Surrounding Dicamba

Farmers consider alternative dicamba products after the 9th Circuit Court blocks three registrations.

Syngenta’s Tavium is still available for use and the University of Missouri Extension says that they are getting questions about application and registration. The product is not included in the lawsuit because it was approved in 2019 and does not expire until the end of the year. It is also a different type of product because it is pre-packaged and pre-mixed.

While it is currently still an option, Extension says that any dicamba-related decisions from the EPA could effect future use.

Tennessee confirms cases of dicamba-resistant Palmer amaranth.

University of Tennessee Extension says that the threat is still considered low and says the weeds can survive up to 2.5 times the labeled dicamba spray rates. One weed specialist says that farmers have less tools in the tool box and need to prioritize stewardship to ensure continued use of the products currently available.
