Get the Facts about Root Protection and Yield

So what drives yield? It's the total genetic package - elite germplasm, high-performance traits and a technology integration process that brings them together without sacrificing yield.

In a word, it's Agrisure®.

High-Performance Traits. Elite Genetics. Advanced Technology Integration.

Get the facts:

1. Rootworm traits don't make your yield - they protect your yield.

  • 2007 Iowa State University (ISU) corn rootworm trials1 show there is not a clear correlation between root ratings and yield.
  • NEWS RELEASE
  • FACT SHEET
  • ISU STUDY

2. Not all trait technologies are integrated equally.

  • Adding a trait does not always have a positive impact on yield. Adding Herculex® RW to Herculex I actually decreased yield performance in 2007 ISU corn rootworm trials2.
  • When Syngenta breeders added the Agrisure RW trait to hybrids with Agrisure CB/LL, they actually increased yields an average of 3.7 bu/A in the absence of rootworm pressure3.




  • Adding Herculex RW to Herculex I hybrids decreased yields an average of 7.8 bu/A from the same hybrid without Herculex RW4.

2 Evaluation of corn Rootworm Hybrids, Iowa State University, Southeast, Northeast, and Northwest Research and Demonstration Farms.

3 2007 Syngenta grower strip trial comparisons. Hybrids compared were within three days RM of one another.

4 All comparisons from 2007 Syngenta strip trials. Yield increase/decreases are based on comparisons between Agrisure CB/LL hybrids and Agrisure CB/LL/RW hybrids of similar genetics. Herculex comparisons consisted of 26 strip trial comparisons between 34A16 Herculex I and 34A18 Herculex XTRA hybrids.

5 Average yield increase when comparing isoline hybrids at 133 grower strip trials comparisons in 2007 where rootworm feeding was not present in untreated checks.
