EPA approves Syngenta's Agrisure corn trait

Agriculture.com Staff 12/04/2008 @ 11:50am

Syngenta officials announced this week the Environmental Protection Agency (EPA) has granted registration approval for its new Agrisure corn trait that Syngenta will include in stacks with the Agrisure CB/LL trait for the control of a broad spectrum of lepidopteran corn pests.

Company officials call he approval a "key milestone" in bringing to market a new mode of action for insect control in corn, according to a Syngenta report.

Pending all remaining regulatory and key import approvals, hybrids containing the new trait are anticipated to be available for planting in spring 2010. The trait will only be available stacked with either the Agrisure 3000GT trait stack for control of European corn borer, corn rootworm and glyphosate or glufosinate herbicide tolerance, or the Agrisure GT/CB/LL stack for control of European corn borer with glyphosate and glufosinate herbicide tolerance.

Tracy Mader, marketing manager for Agrisure Corn Traits, says the technology, which represents a new mode of action for insect control in corn, is expected to eliminate resistance concerns through the use of a new mode of action.

"Current corn insect control traits use Cry proteins," Mader says in a company report. "Although Vip3A targets pests in a manner similar to the Cry class of proteins, the two types of protein attack different sites on the pest's gut and have distinct modes of action.

"Just as using different herbicides can help reduce the potential for weeds developing resistance to herbicides, using different modes of action for insect control can reduce the risk for resistance development to these critical trait technologies."
