* Comparisons from 2007 customer side-by-side yield checks and from 2007 Pioneer Product Advancement Trials.

** Income Advantage / Acre is calculated with the price of corn at $3.10 per bushel and drying costs of $0.04 per point of moisture above 15%.

Results may not predict future performance and may not be complete. Product responses are variable and subject to any number of environmental, disease and pest pressures.

HX1 - The Herculex I insect protection trait offers a high level of resistance to European corn borer, southwestern corn borer and fall armyworm. The gene also offers very good resistance to black cutworm and western bean cutworm, and moderate resistance to corn earworm.

HXX - Hybrids that contain HXX® provide protection against European corn borer, southwestern corn borer, black cutworm, fall armyworm, western bean cutworm, lesser corn stalk borer, southern corn stalk borer, and sugarcane borer; suppresses corn earworm; and also provide protection from larval injury caused by western corn rootworm, northern corn rootworm and Mexican corn rootworms.

LL - Contains the LibertyLink® gene for resistance to Liberty® herbicide.

RR2 - Contains the Roundup Ready® Corn 2 trait that provides crop safety for over-the-top applications of labeled glyphosate herbicides when applied according to label directions.

YGCB - The YieldGard® Corn Borer gene offers a high level of resistance to European corn borer, southwestern corn borer and southern cornstalk borer. The gene also offers a moderate level of resistance to corn earworm and common stalk borer; above average resistance to fall armyworm.

YGPL - Hybrids with the YieldGard® Plus trait control European corn borer, southwestern corn borer, southern cornstalk borer and sugarcane borer, and suppress corn earworm, fall armyworm and stalk borer along with providing control of western corn rootworm, northern corn rootworm, and Mexican corn rootworm throughout the larval feeding period.
