The U.S. Court of Appeals for the Ninth District issued a ruling June 3 vacating U.S. registrations of several important crop protection products (including low-volatility dicamba) used by soybean farmers to manage weeds.

The ruling pertains specifically to the Environmental Protection Agency’s (EPA) 2018 registration decision on these products set to expire in December. 

The court contends the EPA did not meet its legal obligations when issuing the conditional registrations under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA).

So what
The Iowa Soybean Association strongly advocates the need for farmers to have access to a variety of tools in the toolbox to grow soybeans while being stewards of those products, the land and water and good neighbors by avoiding off-target impacts.

The ruling vacating the ability to use important products needed to manage weeds could not come at a worse time for Iowa soybean farmers. Given the timeliness of planting this year’s soybean crop, many farmers are quickly approaching both the number of days and crop maturity (v4) guidelines in which to use these products.

Now what
The court’s decision seeks to immediately vacate (end) the registrations for XtendiMax (Bayer), FeXapan (Corteva) and Engenia (BASF). However, this was only the Court’s decision. The decision can be implemented only after parties in the case have exhausted options or time limit to request a rehearing of the case.

The court acknowledged the practical and adverse effects of its decision on farmers. Acknowledgment and expressions of sympathy, however, are of little value to farmers who are already struggling to manage producing a soybean crop under very challenging circumstances.

The Iowa Soybean Association is fully engaged in this developing situation. We are working real-time with the American Soybean Association, state and federal regulatory officials and industry partners to understand the totality of this ruling and next steps.

We are also considering any and all action steps that can be taken to minimize the impact on farmers who, in good faith, planted soybeans with specific traits fully expecting to match those plantings with specific weed management systems.

We will communicate with soybean farmers options and timelines impacted by this decision to ensure they can manage weeds safely, successfully and sustainably.
