Herculex® Insect Protection

The Herculex® family of insect protection traits provides farmers with protection against a broad spectrum of insect pests that annually cause millions of dollars of damage in crops.  Following U.S. federal agency guidelines, these traits went through extensive testing and regulatory evaluation for food, feed and environmental safety prior to commercialization.  DuPont is committed to the safety of its products and complies with regulatory systems in each country where its products are sold.

Herculex I

The Herculex I trait was the first in a new generation of Better Bt choices available in Pioneer® brand corn hybrids. The Herculex I trait is the only Bt that helps control western bean cutworm and black cutworm. It also provides excellent resistance against a variety of insect pests including European corn borer, southwestern corn borer and fall armyworm, as well as moderate resistance to corn earworm.

Herculex RW

Herculex RW rootworm protection is a Bt trait that offers a high level of protection against northern, western and Mexican corn rootworm. It provides season-long rootworm protection for the entire root system to safeguard yield potential. This unique trait, which includes two proteins instead of one, controls rootworm larvae and reduces adult rootworm beetle emergence by an average of 92 percent. This reduces the risk of silk-clipping and late-season feeding.

Herculex XTRA

Herculex XTRA offers the broadest spectrum of “in-the-seed” above and below ground insect control available by combining Herculex I and Herculex RW insect protection traits. Pioneer brand corn hybrids with Herculex XTRA offer the industry’s broadest in-plant insect protection, controlling corn borers, western bean cutworms, black cutworms, corn rootworms and more.
