The Dicamba Papers: Key Documents and Analysis

Print Email Share Tweet

Dozens of farmers around the United States are suing the former Monsanto Co., purchased in 2018 by Bayer AG, and conglomerate BASF in an effort to hold the companies accountable for millions of acres of crop damage the farmers claim is due to widespread illegal use of the weed killing chemical dicamba, use  promoted by the companies.

The first case to go to trial pitted Missouri’s Bader Farms against the companies and resulted in a $265 million verdict against the companies. The jury awarded $15 million in compensatory damages and $250 million in punitive damages.

The case was filed in the U.S. District Court for the Eastern District of Missouri, Southeastern Division, Civil Docket #1:16-cv-00299-SNLJ. The owners of Bader Farms alleged the companies conspired to create an “ecological disaster” that would induce farmers to buy dicamba-tolerant seeds. Key documents from that case can be found below.

The EPA’s Office of the Inspector General (OIG) plans to investigate the agency’s approvals of new dicamba herbicides to determine whether the EPA adhered to federal requirements and “scientifically sound principles” when it registered the new dicamba herbicides.

BACKGROUND: Dicamba has been used by farmers since the 1960s but with limits that took into account the chemical’s propensity to drift and volatilize- moving far from where it was sprayed. When Monsanto’s popular glyphosate weed killing products, such as Roundup, started losing effectiveness due to widespread weed resistance, Monsanto decided to launch a dicamba cropping system similar to its popular Roundup Ready system, which paired glyphosate-tolerant seeds with glyphosate herbicides. Farmers buying the new genetically engineered dicamba-tolerant seeds could more easily treat stubborn weeds by spraying  entire fields with dicamba, even during warm growing months, without harming their crops. Monsanto announced a collaboration with BASF in 2011. The companies said their new dicamba herbicides would be less volatile and less prone to drift than old formulations of dicamba.

The Environmental Protection Agency approved the use of Monsanto’s dicamba herbicide “XtendiMax” in 2016. BASF developed its own dicamba herbicide that it calls Engenia. Both XtendiMax and Engenia were first sold in the United States in 2017.

Monsanto started selling its dicamba-tolerant seeds in 2016, and a key claim by the plaintiffs is that selling the seeds before regulatory approval of the new dicamba herbicides encouraged farmers to spray fields with old, highly volatile dicamba formulations. The Bader lawsuit claims: “The cause of such destruction to Plaintiff Bader Farms’ crops is Defendant Monsanto’s willful and negligent release of a defective crop system – namely its genetically modified Roundup Ready 2 Xtend soybeans and Bollgard II Xtend cotton seeds (“Xtend crops”) – without an accompanying, EPA-approved dicamba herbicide.”

Farmers claim that the companies knew and expected that the new seeds would spur such widespread use of dicamba that drift would damage the fields of farmers who did not buy the genetically engineered dicamba-tolerant seeds. The farmers allege this was part of a scheme to expand sales of the genetically engineered dicamba-tolerant seeds. Many allege the new dicamba formulations sold by the companies also drift and cause crop damage just as the old versions have done.

The EPA issued the following statement to U.S. Right to Know:

“EPA is taking the reports of crop damage related to the use of dicamba very seriously.  We are working with the states and the registrants to better understand the issue so we can address the problem of illegal drift. Considering the incidents that have been reported, we are reviewing the current use restrictions on the label to see what changes can be made so that unwanted exposures will not occur. The underlying causes of the various damage incidents are not yet clear, as on-going investigations have yet to be concluded. But EPA is reviewing all available information carefully. We will rely on the best information available to inform any regulatory change.”
