Syngenta, Dow AgroSciences reach trait cross-licensing agreement

Syngenta and Dow AgroSciences have agreed to cross license their respective corn events for commercialization within their branded seed businesses.

Under the agreement, Syngenta will receive global non-exclusive licenses, with stacking rights, to Dow AgroSciences' Herculex I Insect Protection for broad lepidopteran control and to Herculex RW for corn rootworm control.

Dow AgroSciences will receive global non-exclusive licenses with stacking rights to Syngenta's Agrisure GT trait for glyphosate tolerance, and to its insect control traits Agrisure CB/LL for corn borer and Agrisure RW for corn rootworm. The licenses also include access to Syngenta's Agrisure Viptera trait for broad lepidoptera and to a second-generation trait for corn rootworm control.

Pending Environmental Protection Agency (EPA) approval, the agreement paves the way for the industry's first reduced-refuge stack in Midwestern corn featuring a combination of functionally and structurally different proteins: Cry proteins (Agrisure CB/LL, Herculex I) and a Vip protein (the Agrisure Viptera event). The EPA recently recognized this technology combination by approving a nationwide 20% refuge for hybrid stacks containing the Agrisure Viptera event and either the Agrisure 3000GT triple stack or the Agrisure GT/CB/LL stack. This is a reduction from the 50% refuge previously required in corn and cotton-growing areas in the Southern United States.

The companies did not disclose financial terms of the agreement.
