In an unprecedented application of executive authority, President Donald Trump issued an executive order on February 18, 2026, titled "Promoting the National Defense by Ensuring an Adequate Supply of Elemental Phosphorus and Glyphosate-Based Herbicides." The order invokes the Defense Production Act (DPA), a Cold War-era statute, to classify the production of glyphosate and the mining of elemental phosphorus as matters of national security. This move effectively grants Bayer AG, the parent company of Monsanto, significant legal immunity from ongoing and future litigation related to its glyphosate-based weed killer, Roundup.
The executive order arrives at a critical juncture for Bayer, which has faced a multi-billion dollar legal onslaught from thousands of plaintiffs—including farmers, agricultural workers, and home gardeners—who allege that exposure to Roundup caused them to develop non-Hodgkin lymphoma. By utilizing the DPA, the administration has introduced a formidable legal shield that complicates the path for victims seeking compensation through the American judicial system.
The Mechanism of Immunity Under the Defense Production Act
The Defense Production Act of 1950 was originally designed to ensure the availability of industrial resources for national defense during the Korean War. However, Section 707 of the Act contains a specific provision that protects companies from liability when they act under government direction. The statute states that no person or company shall be held liable for damages or penalties for any act or failure to act resulting directly or indirectly from compliance with a rule, regulation, or order issued pursuant to the Act.
Under the new executive order, the Department of Agriculture (USDA) is directed to contract with Bayer to maximize the production of glyphosate and the extraction of elemental phosphorus. Because Bayer is now operating as a directed contractor for the federal government, the company may be shielded from liability for any harm resulting from its production processes or the products themselves, provided they are produced in compliance with USDA regulations.
Legal analysts suggest that this immunity remains in place even if the underlying government order is later declared invalid by a court. This creates a scenario where, as long as Bayer adheres to the production mandates set by the USDA, it is effectively "off the hook" for health or environmental damages, shifting the burden of risk from the corporation to the public and the federal government.
The Strategic Importance of Phosphorus and Military Ties
The executive order justifies its use of the DPA by highlighting the dual-use nature of elemental phosphorus. While it is a foundational component of glyphosate-based herbicides, it is also a critical material for the defense industry. Section 1 of the order notes that elemental phosphorus is "pervasive in defense supply chains" and is "crucial to military readiness and national defense," citing its use in smoke, illumination, and incendiary devices.
Bayer, through its partnership with Israel Chemicals Ltd., serves as a primary supplier of white phosphorus to the U.S. military. By linking agricultural herbicide production to military incendiary requirements, the administration has framed the entire phosphorus supply chain as a single, indivisible national security asset. This integration allows the federal government to mandate production levels and mining operations that bypass traditional environmental and civil liability hurdles.
The order has received unexpected support from Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. Despite his long history of litigating against corporate polluters and his previous criticisms of glyphosate, Kennedy has signaled his support for the executive order, a move that has surprised many in the public health and environmental advocacy sectors.
Environmental and Health Impacts in Manufacturing Hubs
The legal immunity granted by the DPA is particularly significant for the communities surrounding Bayer’s primary manufacturing and mining facilities. Bayer currently controls approximately 40 percent of the global glyphosate market and 70 percent of the domestic U.S. market. Its operations are concentrated in several key locations, many of which have long histories of environmental contamination.
Muscatine, Iowa
The Muscatine facility has been a site of pesticide and herbicide manufacturing since 1961. It is currently a designated Superfund site, monitored by the Environmental Protection Agency (EPA) and the Iowa Department of Natural Resources. Historical data indicates that the facility has contaminated soil and groundwater with hazardous waste, with toxins detected as deep as 95 feet below the surface. Iowa currently holds the second-highest cancer rate in the United States, according to the 2024 Iowa Cancer Registry, which estimates over 6,100 cancer deaths in the state annually.
Kansas City, Missouri
Bayer’s operations in Kansas City have also faced intense scrutiny. The facility is located near the Kansas River, an area with some of the highest recorded levels of air and water pollution in the country. Before merging with Monsanto, Bayer was fined by the EPA for violating risk management regulations involving the storage of millions of pounds of hazardous substances, including vinyl chloride and formaldehyde.
Luling, Louisiana
Located in the industrial corridor known as "Cancer Alley," the Luling plant is another Superfund site. It operates in tandem with a formaldehyde plant, with the two facilities connected by a pipeline system. Monsanto and Bayer have faced repeated fines for air pollution violations in this region, where local residents report disproportionately high rates of respiratory illness and cancer.
Internal Monsanto communications, surfaced during previous Roundup litigation, revealed that the company maintained a "Cancer Index" to track employees who were diagnosed with the disease following workplace exposure. With the DPA immunity in place, future claims by employees or residents in these "hotspots" may be barred by federal law.
Phosphate Mining and Ecological Degradation in Idaho
The executive order also covers the extraction of phosphate ore, the raw material for elemental phosphorus. Bayer operates a vertically integrated supply chain that includes a phosphorus factory in Soda Springs, Idaho, and nearby mines. These mining operations have transformed the local landscape near Yellowstone and Grand Teton National Parks into what critics describe as a "moonscape."
The environmental toll in Idaho includes:
- Selenium Leaching: Waste from the mines has leached selenium into groundwater and streams, leading to the deaths of livestock and the deformation of fish populations, including the declining Yellowstone cutthroat trout.
- Radioactive Slag: The refinement of phosphate ore produces a byproduct known as slag, which contains elevated concentrations of radioactive material. Historically, this slag was used as construction material for homes and roads in Soda Springs and Pocatello. An EPA study warned that residents in these areas face a 1-in-700 chance of contracting cancer due to gamma ray exposure from the slag.
- Wildlife Displacement: Populations of grizzly bears, wolves, and sage grouse have plummeted in the mining region as their habitat is destroyed or contaminated.
Despite these issues, the administration authorized Bayer to begin operations at the new Caldwell Canyon mine in 2025, further expanding the footprint of radioactive waste production under the protection of the DPA.
The Mosaic Connection and Florida’s Phosphate Crisis
The implications of the executive order extend beyond Bayer to other major players in the phosphate industry, most notably Mosaic. Based in Tampa, Florida, Mosaic is the world’s largest producer of concentrated phosphate crop nutrients, accounting for 74 percent of North American production.
Mosaic’s operations in Central Florida cover 450,000 acres. Approximately 50,000 Floridians live on land that was formerly mined for phosphate. These residential areas are often contaminated with uranium and radium-226, as the "reclamation" process frequently involved simply replacing excavated soil without removing radioactive materials. In 2024, a settlement involving the Oakbridge and Grasslands communities in Lakeland revealed that radiation levels in some subdivisions were 11 to 21 times higher than acceptable limits.
Furthermore, the administration has signaled support for using phosphogypsum—a radioactive waste byproduct of fertilizer production—in road construction. For every ton of fertilizer produced, five tons of phosphogypsum are generated. While the EPA banned the use of this material in 1989, recent policy shifts have sought to permit its use in infrastructure projects, a move currently being challenged in court by the Center for Biological Diversity.
Legislative Counter-Movements and Judicial Challenges
The executive order has sparked immediate legislative pushback in Washington. Congressman Thomas Massie has introduced the "No Immunity for Glyphosate Act," which seeks to explicitly strip Bayer of the protections granted under the Defense Production Act for herbicide manufacturing. Concurrently, Senator Cory Booker has introduced the "Pesticide Injury Accountability Act" to ensure that victims of chemical exposure retain the right to seek damages in court, regardless of executive mandates.
The legislative battle is compounded by a looming decision from the Supreme Court. The Court has agreed to hear Monsanto v. Durnell, a case centered on federal preemption. If the Supreme Court rules in Bayer’s favor, it could establish that federal EPA labeling laws preempt state-level warning requirements, effectively shielding all pesticide manufacturers from failure-to-warn lawsuits nationwide.
Analysis of National and Economic Implications
The convergence of the executive order and the potential Supreme Court ruling represents a systemic shift in how corporate liability is managed in the United States. By framing chemical manufacturing as a national defense priority, the administration is prioritizing industrial output and supply chain stability over individual litigation rights and environmental standards.
Economically, the move stabilizes Bayer’s financial position, which has been severely strained by litigation costs and declining stock value since the Monsanto acquisition. However, the long-term costs may be shifted to the public health system and federal environmental cleanup programs. If the "No Immunity for Glyphosate Act" fails to pass, the precedent set by using the DPA in this manner could allow other industries to seek similar "national defense" classifications to evade civil liability for environmental or health-related damages.
As the 2026 legislative session continues, the tension between national security mandates and consumer protection remains a central theme in the debate over the future of American agriculture and industrial policy.
