An Arizona District Court vacated the 2020 registration of over-the-top dicamba products, so the Environmental Protection Agency issued an Existing Stocks Order. The order allows limited sale and distribution of dicamba products that were already in possession of growers or in trade channels outside of the control of pesticide companies by February 6.

The order also prohibits the use of these dicamba products except where the use is consistent with the previously approved labeling, which included measures intended to reduce environmental damage caused by offsite movement of the pesticide.

The EPA issued the order after receiving enough evidence that millions of gallons of OTT dicamba had already entered the trade channels before February 6. Plus, growers aren’t able to switch to other options due to the timing of the Arizona court’s decision.

The order applies only to dicamba formulations designed to use over the top of dicamba-tolerant soybeans and cotton.
