Syngenta Seeds, Inc., has submitted to the U.S. Environmental Protection Agency (EPA) an application for the registration of its Agrisure Viptera 3220 trait stack, featuring two modes of action against all major lepidopteran corn pests and a reduced refuge of 5 percent in the Midwestern Corn Belt.

The Agrisure Viptera 3220 trait stack combines the forthcoming Agrisure Viptera trait, featuring the breakthrough Vip3A protein, the industry's first "non-Cry" (non-crystalline) insect control protein and a completely new mode of action in corn. In addition, the stack contains the trusted and tested Agrisure CB/LL trait, the Bt11 event, which has been protecting corn from European corn borer for more than 10 years. The Agrisure GT trait for glyphosate tolerance and the Herculex I trait for corn borer round out this stack.
