‘Pesticide Safety Decisions Must Remain Grounded in Science’: Agriculture Reacts to Supreme Court Roundup Ruling

The U.S. Supreme Court’s decision in Monsanto v. Durnell is being hailed by agricultural organizations and crop protection stakeholders as a landmark victory for science-based regulation, while drawing criticism from environmental and pesticide-reform advocacy groups that argue the ruling limits legal recourse for individuals alleging harm from glyphosate exposure.

The ruling, issued June 25, held that the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preempts state-law failure-to-warn claims when the U.S. Environmental Protection Agency (EPA) has determined a particular warning is not required on a pesticide label. The decision is expected to significantly reduce thousands of pending lawsuits against Bayer, which acquired Monsanto and the Roundup brand in 2018.

In a statement following the decision, Bayer called the ruling “good for science, farmers, and industries that depend on regulatory clarity for innovation.”

The company added that the decision “should help significantly contain the Roundup litigation after nearly a decade of legal battles” and is expected to result in the dismissal of current warning-based claims while barring future failure-to-warn lawsuits.

For much of agriculture, the decision represents more than a legal victory for Bayer. Industry organizations say it reinforces EPA’s authority as the nation’s pesticide regulator and preserves a uniform national framework for pesticide labeling.

Ag Retailers, Grower Groups Applaud Regulatory Certainty

The Agricultural Retailers Association (ARA) was among the first agricultural organizations to praise the ruling.

“This decision protects the entire agricultural supply chain,” said Daren Coppock, ARA President and CEO. “When ag retailers and applicators comply fully with an EPA-approved label, they should not be punished for following the law.”

Coppock added that the ruling ensures pesticide safety decisions remain “grounded in science,” reflecting Congress’ intent when FIFRA was enacted.

ARA has long argued that allowing state courts to impose warning requirements beyond those approved by EPA would create conflicting regulatory standards, increase liability exposure, and complicate compliance for retailers, applicators, manufacturers, and growers alike.

CropLife America (CLA), which filed an amicus brief in the case, similarly emphasized the importance of consistent pesticide labels nationwide.

“We are pleased that today’s decision recognized the congressionally mandated role of the United States Environmental Protection Agency to approve consistent and science-based pesticide labels,” CLA said in a statement.

The organization noted that regulatory certainty is essential to continued investment in crop protection innovation, research, manufacturing, and product development. CLA also argued that a predictable federal framework supports U.S. agricultural competitiveness and helps ensure farmers maintain access to effective crop protection tools.

The American Soybean Association (ASA) and National Corn Growers Association (NCGA) likewise welcomed the Court’s decision, emphasizing the importance of a uniform regulatory system.

“Farmers depend on clear, consistent labeling and a uniform regulatory framework to use pesticides safely and responsibly,” ASA said.

The organization noted that EPA and regulatory authorities around the world have repeatedly concluded that glyphosate does not pose a cancer risk when used according to label directions. ASA argued that state-level warning requirements have created a patchwork of regulations that can undermine confidence in the regulatory process and restrict access to key weed management tools.

“This is great news for all farmers in the country,” said Jed Bower, Ohio farmer and NCGA president. “Today’s decision reaffirms that FIFRA is the law of the land and states cannot add undue and unproven requirements not backed by science.”

The National Association of Wheat Growers (NAWG) echoed similar concerns.

“This decision is a win for farmers and the broader agricultural community,” said NAWG CEO Sam Kieffer. “Farmers depend on clear, predictable, science-based regulations and continued access to effective crop protection tools. Today’s decision reaffirms that EPA’s label, based on a rigorous process of scientific review, is the law.”

NAWG said the ruling provides important clarity regarding the relationship between federal pesticide regulation and state tort law while reaffirming EPA’s role in evaluating scientific evidence and establishing labeling requirements.

Collectively, industry organizations framed the decision as a critical affirmation of federal regulatory authority and a safeguard against what many view as an increasingly fragmented state-by-state approach to pesticide regulation.

For many agricultural stakeholders, concerns extended beyond glyphosate itself. Several groups warned during the case that allowing state-level warning requirements to supersede EPA decisions could have broader implications for numerous crop protection products and future innovations entering the market.

Advocacy Groups Warn of Reduced Accountability

Not all reactions were positive.

Environmental, consumer, and agricultural reform advocacy organizations criticized the decision, arguing it weakens legal protections and limits accountability for pesticide manufacturers.

As You Sow, a shareholder advocacy organization focused on environmental and social responsibility, said the ruling “significantly limits” the ability of states and individuals to pursue failure-to-warn claims. Danielle Fugere, the group’s president and chief counsel, called state litigation “one of the last meaningful checks on pesticide safety in this country.”

Farm Action, an agricultural policy advocacy organization, expressed disappointment with the ruling. “This ruling weakens protections for farmers, farmworkers, and the public,” said Farm Action President Angela Huffman, arguing that farmers have alternatives beyond Bayer’s products and should not be used as justification for granting corporations legal immunity.

Beyond Pesticides also criticized the decision. Executive Director Jay Feldman called it “a tragic setback for public and environmental health,” arguing that litigation serves as an important mechanism for holding manufacturers accountable when health concerns emerge.

Several organizations associated with the Make America Healthy Again (MAHA) movement likewise condemned the ruling, contending that it places excessive reliance on federal regulatory determinations and reduces avenues for legal challenges involving pesticide products.

What Comes Next

The Supreme Court’s decision is expected to have immediate implications for pending Roundup litigation and could influence future cases involving federally regulated pesticide products.

For agricultural retailers, manufacturers, and grower organizations, the ruling provides long-sought clarity regarding EPA’s authority over pesticide labeling and the relationship between federal regulation and state tort claims.

At the same time, advocacy groups are signaling that debates surrounding glyphosate, pesticide labeling, and manufacturer liability are far from settled.

As legal challenges subside, attention is likely to shift toward regulatory policy, state legislation, investor activism, and ongoing discussions over the future of pesticide regulation in the United States.
