Pioneer® brand hybrids with
Herculex XTRA Protection significantly better than competitors
in field trials for second straight year
Research conducted by the
University of Illinois shows that Pioneer® brand corn
hybrids with Herculex® XTRA traits were significantly better at
protecting corn roots than hybrids with the YieldGard® VT Triple
trait under very high rootworm pressure.
In University of Illinois trials in 2006 and 2007, Pioneer
hybrids with the Herculex XTRA trait showed consistent,
excellent protection against corn rootworm.
"The University of Illinois
research results confirm that, in
Pioneer hybrids, Herculex XTRA is The Better BtTM" DuPont
Vice President and General Manager and President of Pioneer Dean
Oestreich says. "Pioneer hybrids with the Herculex XTRA trait
provide proven, excellent protection to corn roots. Growers can
plant hybrids with the Herculex XTRA trait and feel confident
that this will protect corn roots, regardless of the level of
rootworm pressure."
The University of Illinois results match other studies conducted
this season by Pioneer Agronomy Sciences across 16 locations
throughout the Corn Belt, showing Pioneer hybrids with the
Herculex XTRA trait consistently provide excellent rootworm
control in all pressure levels better than or equal to other
in-plant corn rootworm traits.
In addition, these studies show that the Pioneer hybrids with
the Herculex XTRA trait provide consistent results in protecting
corn roots from rootworm damage regardless of rootworm pressure
under a range of growing conditions. This complements studies
done in previous years showing consistent, excellent protection
from the Herculex XTRA trait against corn rootworms.
The University of Illinois trials, released in its newsletter
dated Friday, August 17, 2007, evaluated a variety of corn
rootworm management technologies including in-plant biotech
traits, insecticide seed treatments, and granular and liquid
insecticides. All were compared to unprotected checks. Test
results were released from Monmouth, DeKalb and Urbana, Illinois
In the Urbana, Ill., location, Pioneer hybrids with Herculex
XTRA insect protection provided superior protection to DeKalb®
brand hybrids with the YieldGard® VT Triple trait. Pioneer®
hybrid 33T59 with the Herculex® XTRA trait had a root rating of
0.49, significantly better than the DeKalb product DKC61-69 with
the YieldGard VT Triple trait that rated 0.84. The check hybrids
had root ratings as high as 2.86, showing very high corn
rootworm infestation. Evaluations were based on a 0-3 root node
injury scale.
In 2007 Pioneer trials, Pioneer hybrids with the Herculex XTRA
trait also showed a significant difference between it and
competitors in high corn rootworm pressure situations. In a
study in Readlyn, Iowa, root ratings for Pioneer hybrids with
the Herculex XTRA trait were 0.34, while DeKalb hybrids with the
YieldGard Plus trait were 0.80 and Northrup King® hybrids with
the Syngenta Agrisure® RW trait were 1.47. The check corn
hybrids at the Readlyn site averaged 2.65, indicating high
pressure.
In the remaining Pioneer trials, Pioneer hybrids with the
Herculex XTRA trait showed consistent and excellent results.
Herculex® XTRA protection is a combination of Herculex® RW and
Herculex® I traits for the broadest in-plant insect protection
in the industry. In addition to defending the plant by
controlling western, northern and Mexican corn rootworm,
Herculex XTRA helps protect against European and southwestern
corn borer, western bean cutworm, black cutworm and fall
armyworm.
"Pioneer customers can be assured that the traits and the high
yielding genetics offered in Pioneer products have been tested
across a broad range of geographies and under a variety of
growing conditions," Oestreich says. "The Pioneer focus is to
bring the greatest value to each acre of land with the latest
technologies and greatest choices, year after year after year."
