FMC Corporation Receives Industry's First Dual Mode of Action Herbicide Classification for Rimisoxafen

Core Insights - FMC Corporation's herbicide rimisoxafen has been classified as a dual mode of action herbicide by the Herbicide Resistance Action Committee (HRAC), marking a historic milestone in the crop protection industry [1][2] - This classification highlights rimisoxafen's ability to inhibit both phytoene desaturase (PDS) and solanesyl diphosphate synthase (SDPS), making it a powerful tool against herbicide-resistant weeds [2][3] Company Developments - FMC's executive vice president and chief technology officer emphasized that rimisoxafen effectively controls palmer amaranth and waterhemp, which are resistant to multiple herbicide classes, thus providing farmers with a vital solution [3] - Rimisoxafen is primarily designed for broadacre crops such as corn, soybean, cereals, pulses, and sunflower, offering effective control of troublesome broadleaf weeds [3] - The herbicide was discovered at FMC's Stine Research Center and represents the third novel herbicide developed by the company for regulatory submission in recent years, following Isoflex and Dodhylex [4] Industry Context - The classification of rimisoxafen addresses the growing challenge of herbicide resistance in agriculture, particularly against economically damaging weeds like palmer amaranth, which has developed resistance to eight different herbicide modes of action [3] - The dual mode of action of rimisoxafen creates a significantly higher barrier to resistance development compared to single mode of action herbicides, enhancing its effectiveness in crop protection [3]
