EPA approves Syngenta’s new corn trait stack with 5% refuge

EPA has granted registration approval for Syngenta’s new Agrisure 3122 corn trait stack. The stack features two modes of action against both corn borer and corn rootworm, with a structured refuge of only 5% in the Corn Belt.

The Agrisure 3122 trait stack includes the Agrisure CB/LL trait for European corn borer; the Herculex I trait for corn borer; the Agrisure RW trait, which protects against corn rootworm; the Herculex RW trait for corn rootworm; and the Agrisure GT trait for glyphosate tolerance.

Syngenta states that Agrisure 3122 “is designed for geographies where corn rootworm management is a significant concern for growers.” The new product will be called Agrisure 3122 Refuge Renew, for its 5% refuge requirement. Syngenta also has submitted a 5% blended refuge-in-a-bag version of the Agrisure 3122 trait stack, to be called Agrisure 3122 E-Z Refuge, for EPA approval. In cotton-growing areas, this trait stack will require a 50% refuge.

Syngenta expects that hybrids with the Agrisure 3122 trait stack will be available for the 2012 growing season from its seed brands Garst, Golden Harvest and NK, pending key import market approvals.
