Syngenta in North America announced that the U.S. Environmental Protection Agency (EPA) has granted registration approval for the Agrisure Viptera 3220 trait stack, which offers corn growers dual modes of action against above-ground (lepidopteran) insect pests.
“With this approval, Syngenta offers growers more control of above-ground insects with a reduced five% structured refuge,” said David Morgan, Syngenta region director of North America and president of Syngenta Seeds, Inc. “Not only do growers enjoy greater productivity through reduced refuge, they also will get more yield benefits from the Agrisure Viptera trait and its superior control of the multi-pest complex.”
The revolutionary Agrisure Viptera 3220 trait stack includes the breakthrough Agrisure Viptera trait, a completely new mode of action in corn as the first Vip3A insect control protein. In 2010 Syngenta trials, triple stack hybrids with the Agrisure Viptera trait outyielded competitive triple stack hybrids by more than 9 bushels per acre on average. In addition, the Agrisure Viptera 3220 trait stack contains the trusted Agrisure CB/LL trait, which has been helping to protect corn from European corn borer for more than 10 years while offering glufosinate tolerance, the Herculex I trait for corn borer protection and the Agrisure GT trait for glyphosate tolerance.
The Agrisure Viptera 3220 trait stack is designed for geographies where corn rootworm management is not a primary issue. Syngenta anticipates hybrids with the Agrisure Viptera 3220 trait stack to be available for planting in the 2012 growing season pending receipt of all remaining regulatory approvals for cultivation and import markets.
Syngenta also has submitted a 5% blended refuge-in-a-bag version of the Agrisure Viptera 3220 trait stack for EPA approval. Pending receipt of all necessary regulatory approvals and authorizations, this product concept is anticipated to be marketed under the name Agrisure E-Z Refuge.
The Agrisure Viptera 3111 trait stack currently is available for planting in hybrids from the Syngenta seed brands of Garst, Golden Harvest and NK and is also being made available through licensing agreements with more than 150 local and independently owned seed companies.
The Agrisure Viptera trait is approved for cultivation in the U.S., Canada and Brazil, and is approved for import into Australia, Canada, Mexico, the Philippines, Japan, Taiwan and South Korea.
