Following a significant legal decision by the U.S. District Court of Arizona on 6 February 2024, the Environmental Protection Agency (EPA) has taken swift action regarding the use of dicamba, a widely used herbicide in agriculture. The court's decision vacated the 2020 registrations of three major dicamba products, citing concerns over their environmental and economic impacts.
Immediate EPA Action: Existing Stocks Order
In response to the ruling, the EPA issued an Existing Stocks Order on 14 February 2024, to manage the immediate aftermath for growers. This order permits the limited sale and distribution of existing dicamba stocks that were in possession of growers or within the distribution channels as of 6 February 2024. It's a crucial step to ensure that the use of these products aligns with previously approved labelling, aiming to mitigate potential risks associated with off-target movement.
Background of Dicamba Use and Controversy
Dicamba has been a cornerstone in the fight against broadleaf weeds, registered for use in various crops including corn, cotton, and soybeans. Its OTT application on dicamba-tolerant crops, approved in 2016, has been contentious due to reports of unintended damage to nearby non-tolerant crops. Despite EPA's efforts to amend the registrations and implement measures to prevent off-target movement, the 2020 registrations were challenged, leading to the recent court decision.
Purpose and Limitations of the Existing Stocks Order
The EPA's Existing Stocks Order is specifically tailored for the 2024 growing season, acknowledging the challenges faced by growers who have already invested in dicamba-tolerant seeds and products. The order outlines strict guidelines for the use of existing dicamba stocks, emphasizing the need for compliance with measures designed to minimize environmental and collateral damage.
Looking Forward: EPA's Ongoing Evaluation
The EPA is committed to updating the public and stakeholders as it evaluates the implications of the court's decision and considers future actions related to dicamba use. The agency's goal is to balance agricultural needs with environmental protection and community well-being, ensuring that herbicide use is conducted safely and responsibly.
