"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.
