Stewardship requirements

Both Corteva Agriscience and Pioneer Seeds product stewardship approach means responsible management of the life cycle of our technologies from initial research to the discontinuation of a product.

Corteva Agriscience requires that growers comply with regulations, Corteva Agriscience policies, and crop management strategies for Optimum GLY herbicide tolerant hybrids.

Growers will be required to complete applicable stewardship training and complete a Technology Use Agreement (TUA) before obtaining, planting or growing seed containing the Optimum GLY trait. The Technology Use Agreement is available on the Corteva website.
