Syngenta has unveiled preliminary data from its 2008 trials designed to evaluate the efficacy of its new broad-spectrum lepidopteran corn pest control trait, event MIR162. The company also announced that the new trait will be known as the Agrisure Viptera trait.
The Agrisure Viptera trait recently was granted registration approval by EPA. Pending all remaining regulatory and key import approvals, hybrids containing the Agrisure Viptera trait are anticipated to be available for planting in spring 2010.
Agronomy Marketing Manager Bruce Battles presented the results of replicated trials in Iowa, Illinois, Nebraska, Kansas, and North Carolina during the American Seed Trade Association’s Corn & Sorghum Research Conference in Chicago, IL. “In addition to measuring yield, we also measured ear damage from naturally occurring pests such as corn earworm,” Battles said. “There was a clear correlation between the level of ear damage and yield increases in the Agrisure CB/LL/RW(European corn borer/LibertyLink/corn rootworm) check vs. the Agrisure Viptera stack. We saw the biggest yield advantages in plots that had higher levels of corn earworm pressure. While the average yield advantage for all plots weighed in at 10.2 bushels per acre, the yield advantage in plots with corn earworm infestation rose to 16.3 bushels per acre.”
The Agrisure Viptera trait will only be available stacked with either the Agrisure 3000GT trait stack for control of European corn borer and corn rootworm with glyphosate and glufosinate herbicide tolerance (GT), or the Agrisure GT/CB/LL stack for control of European corn borer and glyphosate and glufosinate herbicide tolerance.
