Corteva, FMC Partner on New Herbicide Technology to Combat Resistant Weeds

Corteva and FMC Corporation announced a strategic partnership to develop and market herbicide products based on FMC's rimisoxafen technology, designed to combat herbicide-resistant weeds like Palmer amaranth and waterhemp in North and South American corn and soybean crops. Under the agreement, FMC retains technology ownership and will supply the active ingredient to Indianapolis-based Corteva, which will make an initial $200 million prepayment for future supplies. Both companies will independently create proprietary formulations for commercialization before decade's end, pending regulatory approval.

The collaboration addresses mounting farmer losses from resistant weed populations that cost billions annually in reduced yields and increased production expenses. Rimisoxafen features a dual mode of action—classified by the Herbicide Resistance Action Committee as the industry's first—potentially slowing resistance development compared to single-mode herbicides. The partnership reflects broader industry consolidation as crop protection product development grows increasingly costly and complex.
