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
stack*. 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/A**.
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.
*,** All Syngenta strip trial comparisons are completed with
hybrids of similar RMs, adjusted for moisture to +/- 3 points
and of equivalent trait classes unless otherwise noted. Isolines
used for comparison featured identical genetics to the test
hybrids but did not contain the Agrisure Viptera trait.
* Replicated trials consisted of 12 locations, with six
replications per location. Results were averaged across all 12
locations. Replicated trials were located in Colorado, Iowa,
Illinois, Indiana, Kansas, Missouri, Nebraska and North
Carolina.
** Replicated trials consisted of seven locations with six
replications per location. Results were averaged across all
seven locations. Replicated trials were located in Colorado,
Iowa, Indiana, Missouri and North Carolina.
