Our wide selection of HERCULEX® XTRA Insect Protection hybrids combine high-yielding genetics with powerful protection against European corn borer, corn rootworm, western bean cutworm and black cutworm. HERCULEX® XTRA also offers multiple herbicide options. The wide window of protection that HERCULEX® XTRA provides helps top-performing hybrids reach their maximum yield potential. When corn rootworm protection isn’t needed, choose high-yielding HERCULEX® I Insect Protection hybrids.

HERCULEX® I Insect Protection hybrids shield corn hybrids against European corn borer and many other pests. In fact, HERCULEX® I is the only trait that protects against western bean cutworm and black cutworm. HERCULEX® I also provides a wide window of protection and multiple herbicide options for greater control flexibility to help corn hybrids reach their full yield and profit potential.
All HERCULEX® hybrids contain the LibertyLink® trait and many HERCULEX® I Insect Protection hybrids are available as a three-way stack with Roundup Ready® Corn 2 technology.
HERCULEX® XTRA Insect Protection combines high-yielding genetics with the only in-plant insect protection against corn rootworm, European corn borer, western bean cutworm and black cutworm. HERCULEX® XTRA delivers season-long protection for optimum yield potential, agronomic performance and enhanced plant health. Multiple herbicide options with HERCULEX® XTRA offer producers diversified weed control options.
Yield trials conducted over the past several years prove that HERCULEX® XTRA offers not only outstanding performance against corn rootworm, but also delivers exceptional yields. In fact, in 2006 trials, HERCULEX® XTRA hybrids out-yielded their non-traited isoline hybrids by 30 bushels per acre.
All HERCULEX® hybrids contain the LibertyLink® trait and many HERCULEX® XTRA hybrids are available as a Quad-Stack™ with Roundup Ready® Corn 2 technology.

Damage caused by corn rootworm continues to grow throughout the Corn Belt. Traditionally, corn rootworm was a problem in corn-after-corn rotations; now it has adapted itself in many locations to include a corn-soybean rotation. Two types of increasingly troublesome corn rootworm areas include the soybean variant of the western corn rootworm and extended diapause areas of northern corn rootworms.

Originally found only in Colorado and other western states, the western bean cutworm continues to move east. In fact, western bean cutworms have been found as far east as Indiana and Ohio.

Black cutworm is the most damaging cutworm species in corn. Larvae sever roots from plants near the soil line, reducing crop stands and lowering yields. Plants that are cut below ground and larger plants that have been tunneled usually do not recover. Fortunately, the HERCULEX® trait provides the only in-plant protection against black cutworm.

Damage from black cutworm is often most evident in no-till or weedy fields, especially in poorly drained areas. While black cutworm is a threat to nearly every corn-growing region in the United States, the Midwest is particularly at risk of infestations.

Note the dramatic stand difference in this refuge, which came under attack from black cutworm.
