FMC Corporation Celebrates Groundbreaking Classification for Rimisoxafen Herbicide

In a remarkable advancement for agricultural science, FMC Corporation (NYSE: FMC) has been recognized by the Herbicide Resistance Action Committee (HRAC) as the first entity to have its herbicide classified as a dual mode of action product. This historic classification is centered on Rimisoxafen, which falls under HRAC Groups 12 and 32, representing a significant innovation in the fight against herbicide-resistant weeds.

Understanding Dual Mode of Action

Rimisoxafen has garnered attention for its unique ability to target two vital biochemical pathways within plants simultaneously—phytoene desaturase (PDS) and solanesyl diphosphate synthase (SDPS). Unlike traditional herbicides that often rely on a single mode of action, the dual mechanism employed by Rimisoxafen complicates the ability of weeds to survive and develop resistance. This innovation presents a valuable resource for agricultural producers facing the persistent challenge of herbicide resistance.

According to FMC's Executive Vice President and Chief Technology Officer Seva Rostovtsev, “This historic classification of rimisoxafen validates the breakthrough nature of this technology. Studies indicate that this molecule effectively controls stubborn weeds like palmer amaranth and waterhemp, providing farmers with a robust solution against species resistant to several other herbicide classes.”

Combatting Herbicide Resistance

Herbicide resistance has escalated dramatically among various weed species, creating serious challenges for growers worldwide. Palmer amaranth is at the forefront of this battle, having developed resistance against eight distinct herbicide modes of action. The introduction of Rimisoxafen’s dual mode of action represents a transformative shift, establishing a higher barrier against the evolution of resistance compared to single-action herbicides.

Primarily formulated for use in broadacre crops—including corn, soybean, cereals, pulses, and sunflowers—Rimisoxafen is designed to tackle invasive and resistant broadleaf weeds efficiently. This breakthrough herbicide promises to equip farmers with a powerful tool in safeguarding their crops and preserving their livelihoods.

A Look Ahead for FMC’s Innovations

The journey of Rimisoxafen, discovered at FMC's Stine Research Center, marks it as the third novel herbicide advanced for regulatory review in recent years, following the launches of Isoflex® active and Dodhylex™ active. FMC plans to initiate regulatory submissions for Rimisoxafen in crucial markets beginning in 2026, paving the path to provide global farmers with this innovative solution.

FMC Corporation, as a leading agricultural sciences firm, is dedicated to assisting growers in producing food, feed, fiber, and fuel to meet the demands of a growing global population while also accommodating environmental changes. The company remains committed to discovering new herbicides, insecticides, and fungicides—focusing on formulations and pioneering technologies that are beneficial for the planet.

As the agriculture sector confronts increasing pressures from herbicide resistance, FMC Corporation continues to spearhead advancements aimed at securing sustainable crop production and improving economic resilience for farmers worldwide.
