Feb. 14, 2024 Dicamba Update: In a news release from ASA titled “ASA Applauds EPA Existing Stocks Order for Dicamba Ahead of Soy Planting”, the announcement is made that the US-EPA “has declared farmers can accept ‘existing stocks’–previously registered pesticide products currently in the U.S. that were packaged, labeled, and released for shipment prior to the Feb. 6 court ruling–” of dicamba. The existing stocks order also clarified that dicamba products already in the possession of distributors, coops, and other parties for sale before the Feb. 6 date of the cancelled dicamba registration can be sold and distributed, within set guidelines specified in the order. ASA also asks for the administration’s support of an appeal of the Feb. 6 ruling.

Feb. 15, 2024 Dicamba Update: On Feb. 14, 2024, the US-EPA issued an Existing Stocks Order for Dicamba Products Previously Registered for Over-the-Top Use on Dicamba-Tolerant Cotton and Soybeans, which contains the pertinent provisions for the disposition of any existing stocks of formerly registered dicamba products. Of special importance is the information in Table 1 of the above order, which contains the end dates for sale and distribution of existing stocks of dicamba products as well as the end dates for the use of those existing stocks in U.S. states.
