Preliminary results from the 2006
corn harvest indicate that Monsanto’s YieldGard® Rootworm
insect-protected corn hybrid systems, including YieldGard
Rootworm and YieldGard Plus, are delivering outstanding yield
and insect protection to farmers and outyielding competitive
trait and soil insecticide systems.
“Farmers depend on corn yield for
their profitability, and we’re proud that
Monsanto’s YieldGard
Rootworm Corn technologies are protecting yield and delivering
superior results compared with competitive product offerings,”
said Ernesto Fajardo, Vice President of Crop Production for
Monsanto.
Extensive Field Testing Program
During the 2006 growing season,
Monsanto coordinated head-to-head field trials of YieldGard
Rootworm technologies with competitive treatments, including
comprehensive comparisons with the Herculex® trait technology.
The data generated was designed to test both the specific
performance of the rootworm treatments, including a systematic
measurement of insect feeding damage, as well as evaluate the
germplasm and trait system yields. The intent of this evaluation
program is to measure the total yield of each insect control
trait in combination with the specific genetics of the seed in
which it is used. This systematic testing, using head-to-head
plots across broad testing locations, provides a comprehensive
performance indicator that most closely mirrors results farmers
would expect to see on their farms.
Delivering Yield through Better
“System” Performance
Preliminary harvest results from
more than 600 trial comparisons highlight that Monsanto’s
prowess in breeding better corn combined with the company’s
YieldGard Rootworm insect-protected corn technologies are
offering farmers a superior corn seed product when compared with
competitive trait offerings. These head-to-head results indicate
that:
- On a comparison basis,
Monsanto’s system (including both seed genetics and trait
technologies) outyielded Pioneer Hi-Bred’s system on more
than 7 out of 10 acres, or 77.9 percent of the time.
- Monsanto’s YieldGard Plus
delivered 11.5 bushels more per acre when compared with
Herculex XTRA technology in 465 head-to-head field
comparisons.
- Monsanto’s YieldGard
Rootworm delivered 12.1 bushels more per acre when compared
with Herculex RW technology in 138 head-to-head field
comparisons.
Monsanto’s YieldGard Rootworm and
YieldGard Plus corn technology systems also delivered 14.6
bushels more per acre when compared with leading soil-applied
insecticide system offerings including Force®, Aztec®, Lorsban®
and others in 502 head-to-head field comparisons.
Root Efficacy
Preliminary results also highlight
that Monsanto’s YieldGard Rootworm insect-protected corn
technologies are offering farmers similar root protection
compared with competitive trait offerings, and superior root
protection compared with soil-applied insecticide offerings. The
roots were evaluated using the 0-3 node-injury scale as a means
of quantifying the percentage of nodal roots that had been
pruned. It is generally accepted that the economic threshold is
0.25 root rating on the node-injury scale. These results
indicate that:
- Monsanto’s YieldGard
Rootworm and YieldGard Plus technologies had an average
root rating of 0.17 when compared head-to-head with
Pioneer’s Herculex Rootworm or Herculex XTRA technology,
which had an average root rating of 0.20.
- Monsanto’s YieldGard Rootworm and YieldGard Plus Corn
technologies had an average root rating of 0.19 compared
with leading soil-applied insecticide offerings which
had an average root rating of 0.57.
“Farmers select hybrid and trait
seed systems based on which combinations will provide the
greatest yield potential,” stated Clint Pilcher, Corn Technology
Development Manager for Monsanto.
“Insect protection traits will not
improve the yield potential of poor hybrid genetics,” Pilcher
said. “Insect traits simply help a hybrid reach its genetic
potential within a given year and environment.”
While YieldGard Rootworm and
Herculex Rootworm technologies are both effective corn rootworm
control technologies when compared to soil applied insecticides,
farmers consider the entire hybrid and technology seed package
when it comes to choosing the products for their farm.
“YieldGard Plus hybrids are delivering higher yielding system
benefits to farmers across the Corn Belt,” Pilcher noted.
Monsanto’s YieldGard Rootworm
Corn technology was introduced in 2003 and YieldGard Plus was
launched in 2004. YieldGard Plus contains both rootworm and corn
borer technologies providing farmers with above and below ground
insect protection. In 2006, Monsanto’s YieldGard Rootworm and
YieldGard Plus technologies were used by more than 60,000 U.S.
corn farmers to protect yield on more than 10 million acres.
