EPA approves new Syngenta corn trait stack featuring dual modes of action

Syngenta in North America announced that the U.S. Environmental Protection Agency (EPA) has granted registration approval for the Agrisure3122 trait stack. The Agrisure3122 stack offers growers dual modes of action against both corn borer and corn rootworm with a structured refuge of only five percent in the Corn Belt region of the United States.

“With this approval, Syngenta now offers growers a reduced-refuge trait stack featuring dual modes of action for both corn rootworm and corn borer,” 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 can also help safeguard trait technology and efficacy into the future.”

The Agrisure 3122 trait stack includes the trusted Agrisure CB/LL trait, which has been helping to protect corn from European corn borer for more than 10 years; the Agrisure RW trait, which protects against corn rootworm; the HerculexI trait for corn borer;  the HerculexRW trait for corn rootworm; and the Agrisure GT trait for glyphosate tolerance.

The Agrisure 3122 trait stack is designed for geographies where corn rootworm management is a significant concern for growers. This product will be marketed as the Agrisure 3122 Refuge Renew trait stack as it includes the added benefit of a five percent structured refuge. Syngenta has also submitted a five percent blended refuge-in-a-bag version of the Agrisure 3122 trait stack for EPA approval. Pending receipt of all regulatory approvals, this RIB product will be marketed as the Agrisure 3122 E-Z Refuge trait stack*. In cotton-growing regions, this trait stack will require a 50% refuge.

Syngenta anticipates hybrids with the Agrisure 3122 trait stack will be available for planting in the 2012 growing season from the Syngenta seed brands Garst, Golden Harvest and NK, pending receipt of remaining key import market approvals.
