FMC and Corteva Partner to Expand Access to Advanced Rimisoxafen Herbicide Technology for Corn and Soybean Growers Across the Americas.

FMC Corporation and Corteva have entered into a co-exclusive strategic supply and licensing agreement aimed at increasing the availability of FMC’s rimisoxafen herbicide technology across North and South America’s corn and soybean markets.

The partnership is expected to provide farmers with a new solution for controlling herbicide-resistant weeds, particularly Amaranthus species, which continue to pose major challenges in soybean and corn production.

"This agreement ensures that more growers across the Americas will have access to rimisoxafen, one of the most innovative herbicide technologies developed in decades. 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," said Leonardo Bastos, FMC vice president and chief marketing officer.

He added: "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 agreement, FMC will retain ownership of rimisoxafen while supplying the active ingredient to Corteva. Each company will develop and market its own exclusive premix formulations for corn and soybean growers in the Americas. Corteva will also provide an initial prepayment of $200 million for future product supply.

"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," said Ericson.

Rimisoxafen features a dual mode of action that helps delay herbicide resistance while improving control of weeds such as palmer amaranth and waterhemp. Commercial sales are expected before the end of the decade, pending regulatory approvals.
