ST. LOUIS 鈥 Farmers, lawyers and scientists said on Tuesday that the future of the weedkiller dicamba now faces fresh uncertainty after an Environmental Protection Agency report revealed that senior Trump-era staffers improperly influenced the decision to re-approve the controversial herbicide in 2018.
The report, released Monday, does more than sow distrust, several said. It undermines the credibility of federal regulators, discourages the participation of outside scientists, encourages lawyers to mount new arguments, and could push farmers to reconsider their crop decisions.
鈥淭he report begs to have further investigation done into it,鈥 said Paul Lesko, a 果酱视频-based attorney working on a wave of dicamba cases. New clients are continually telling him of damage done to their fields by dicamba, he said.
German conglomerate Bayer, a major manufacturer of the chemical, said that it stands by its widely adopted XtendiMax line of dicamba products.

鈥淲e have continued to test and build on the robust scientific data behind this important technology,鈥 the company said on Monday. 鈥淎nd the latest EPA decision in 2020 was based on a significant amount of new data and learnings from recent seasons.鈥
Dicamba, a decades-old chemical, rose to newfound popularity in recent years. Weeds were developing resistance to former herbicide staples, like Roundup, pioneered by Creve Coeur-based Monsanto. Monsanto, looking for alternatives, engineered crop varieties that could withstand dicamba sprayed over them. Bayer purchased Monsanto in 2018.
But farmers soon began to complain that dicamba vaporized and drifted to other fields, harming other plants and crops. Millions of acres of crop damage have now been reported across U.S. farms 鈥 including a $265 million jury ruling last year against Bayer and competitor BASF in favor of a Missouri peach farmer 鈥 all fueling heated controversy and tearing an often bitter rift in the agricultural community.
On Monday, the EPA鈥檚 Office of Inspector General released a report describing a range of procedural inconsistencies that led up to the hot-button decision to uphold the product鈥檚 availability in 2018. 鈥淭his led to senior-level changes to or omissions from scientific documents,鈥 the report said. 鈥淔or instance, these documents excluded some conclusions initially assessed by staff scientists to address stakeholder risks. We also found that staff felt constrained or muted in sharing their concerns on the dicamba registrations.鈥
鈥楽ome level of cynicism鈥
The report, said scientists, farmers and lawyers, is likely to have ripple effects.
Academic weed scientists said it undermines the credibility of the regulatory process that governs herbicides like dicamba, and discourages participation from experts. Some of those sentiments had already been growing in recent years, even before Monday鈥檚 findings came to light.
鈥淭here were a lot of people in the academic community that were disappointed with the decision-making in 2018,鈥 said Andrew Thostenson, a pesticide specialist for North Dakota State University鈥檚 extension service. 鈥淭hat raised some level of cynicism with EPA. It鈥檚 like, 鈥榃hy should I bother providing you with this stuff if you鈥檙e not going to follow through?鈥欌
And the EPA was under a lot of pressure to re-approve dicamba in 2020, Thostenson added, noting that the decision was issued in the week before the presidential election.
Now he鈥檚 bracing for legal challenges to mount.
鈥淚f you鈥檙e in the ag industry or if you find these products useful, it鈥檚 not a good thing,鈥 said Thostenson.
Farmers and seed dealers 鈥 who said they could not speak openly, given their business ties to dicamba products 鈥 agreed that the new details about the 2018 decision cast more murkiness on the future availability of the chemical. Although farmers are already committed to their planting decisions for 2021, in future growing seasons they may be more tempted to explore alternatives that face less risk of getting pulled from the market in a drawn-out tug-of-war.
Lesko, the 果酱视频 attorney, said the findings reinforce the belief that dicamba 鈥渋s not a safe product to be on the market.鈥
But he also said that the types of dicamba clients are changing.
Fewer soybean farmers are coming forward, he said, since so many have adopted the technology 鈥 often to protect themselves from further harm. Damage complaints have shifted to vineyards, plus various fruits, vegetables, and trees that are not resistant to the chemical.
鈥淚t鈥檚 just changing the spectrum,鈥 Lesko said.
