Post-harvest research summaries from multiple Midwestern locations confirm early trial results that showed Pioneer® brand hybrids with Herculex® XTRA are consistently superior to other corn rootworm management options, including other transgenic and soil insecticides.  Pioneer Hi-Bred is a DuPont business.

In the seven university and 11 Pioneer agronomy sciences trials, Pioneer® hybrids with the Herculex® traits were more effective against root damage, compared to hybrids with the YieldGard® traits developed by Monsanto.

In addition, consistency ratings, an indicator of variability of root protection, were noticeably higher for hybrids with Herculex® traits compared to hybrids with YieldGard® traits.

The university research trials were conducted at the University of Illinois (three trials), Iowa State University (one trial) and Purdue University (three trials). 

The benefit of Pioneer® hybrids with Herculex® XTRA is not only protected roots, but higher yields.  Recently published two-year Pioneer agronomy sciences systems trials show that Pioneer hybrids with Herculex® XTRA, on average, had a three-bushel advantage over DeKalb hybrids with YieldGard® Plus.
