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 now available on the Corteva website.
