PHILADELPHIA and INDIANAPOLIS, June 16, 2026
Strategic supply and license agreement will accelerate access for North and South American corn and soybean growers

PHILADELPHIA and INDIANAPOLIS, June 16, 2026 /PRNewswire/ -- FMC Corporation (NYSE: FMC) and Corteva, Inc. (NYSE: CTVA), two leading global agricultural science and innovation companies, today announced a co-exclusive strategic supply and license agreement that will expand access to FMC's rimisoxafen technology across North and South America corn and soybean markets, adding an important new tool to each company's respective herbicide portfolio. This collaboration will enable more growers across the Americas to control herbicide-resistant weeds, including Amaranthus species – the number one weed resistance challenge globally in soybeans and critical in cross-crop pressure in corn – with this groundbreaking dual mode of action herbicide technology.
"This agreement ensures that more growers across the Americas will have access to rimisoxafen, one of the most innovative herbicide technologies developed in decades," said Leonardo Bastos, FMC vice president and chief marketing officer. "By working with Corteva, we are expanding the reach of this breakthrough technology to help growers effectively manage resistant weeds that threaten their productivity and profitability. Together, we are bringing growers a solution they urgently need. At the same time, FMC is committed to unlocking the full global potential of rimisoxafen across additional crops and geographies, reflecting our confidence in this molecule as a cornerstone of our innovation pipeline."
Under the terms of the agreement, which extends through the next decade, FMC retains all rights of ownership to rimisoxafen and will supply Corteva with the active ingredient. Both companies will develop and commercialize their own exclusive premix formulations for the corn and soybean markets across North and South America, while FMC will continue to develop additional rimisoxafen-based products for other crops and geographies globally. Corteva will make an initial prepurchase payment of $200 million USD for product to be supplied by FMC. Together, both companies are committed to ensuring broad availability of this innovative technology and rapid adoption, supporting growers with durable weed management solutions for years to come.
"By collaborating with FMC on rimisoxafen, we are expanding our ability to provide growers with advanced weed control tools that complement our portfolio," said Cynthia Ericson, Corteva vice president, weed control segment. "This agreement supports our long-term strategy of forging new collaborations that drive value for farmers, as well as a unique growth opportunity with attractive economics for Corteva above our current deep crop protection pipeline set to launch over the next decade."
Rimisoxafen's dual mode of action creates a significantly higher barrier to resistance development compared to single mode of action herbicides, providing growers with an essential tool for managing weeds like palmer amaranth and waterhemp that have become resistant to multiple herbicide classes and cost farmers billions of dollars annually in lost yield. First commercial sales are anticipated by the end of the decade, pending applicable regulatory approvals. The Herbicide Resistance Action Committee recently classified rimisoxafen as the industry's first dual mode of action herbicide, recognizing its unique ability to control troublesome broadleaf weeds that threaten crop yields and farm profitability.
Additional terms of the agreement were not disclosed.
