EPA Approves Two Syngenta Stacks Containing the Agrisure Viptera™ Trait

Syngenta reported today that the Environmental Protection Agency (EPA) has granted registration approval for two insecticidal trait stacks that include its new Agrisure Viptera™ trait, which is designed to provide control of a broad spectrum of lepidopteran corn pests. The EPA previously granted registration approval to the single Agrisure Viptera trait in November 2008.

The EPA approvals cover the insecticidal trait combinations in the Agrisure Viptera trait plus the Agrisure® 3000GT stack and the Agrisure Viptera trait plus the Agrisure GT/CB/LL stack products. The Agrisure Viptera trait plus the Agrisure 3000GT stack will provide control of a broad spectrum of lepidopteran corn pests including European corn borer, corn earworm, Western bean cutworm, black cutworm and fall armyworm, along with control of corn rootworm and glyphosate and glufosinate herbicide tolerance. The Agrisure Viptera trait plus the Agrisure GT/CB/LL trait stack will provide the same broad-spectrum lepidopteran control and glyphosate and glufosinate herbicide tolerance, but without corn rootworm control.

In Syngenta trials, Agrisure CB/LL/RW hybrids stacked with the Agrisure Viptera trait provided an average yield advantage of 10.9 bu/A vs. isolines containing only the Agrisure CB/LL/RW stack1. While the 10.9 bu/A yield advantage was an average across all trials, trials in fields with higher levels of corn earworm pressure recorded a yield advantage of 17.5 bu/A2. Syngenta trials also have shown that the Agrisure Viptera trait provides enhanced control of Western bean cutworm, black cutworm, fall armyworm, stalk borer and sugarcane borer.

Pending all remaining regulatory and key import approvals, hybrids featuring these two trait stacks are anticipated to be available for planting in spring 2010.
