Upon receiving full regulatory approvals, the Agrisure Viptera trait will be integrated into commercially available corn hybrids to provide convenient, in-seed protection against a broad spectrum of lepidopteran corn pests.
The Agrisure Viptera trait is unique in its ability to provide improved control of specific pests plus a broad spectrum of insect control.
Preliminary research results at Syngenta show that the Agrisure Viptera trait delivers an additional advantage over competing traits through its added efficacy on pests including:
- Corn earworm
- Western bean cutworm
- Black cutworm
- Fall armyworm
- Common stalk borer
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.
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.
Corn earworm pressure 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.
The Agrisure Viptera trait is not currently registered for sale or use in the U.S. and is not being offered or promoted for sale. This product will not be available for sale until the Environmental Protection Agency has approved regulation and all necessary authorizations have been granted.
