About Herculex® Insect Protection

The Herculex I trait was the first in a new generation of Better Bt choices from Pioneer. It 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. The Herculex I trait is also the only Bt that helps control western bean cutworm and black cutworm.

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%. This reduces the risk of silk-clipping and late-season feeding.

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 hybrids containing Herculex® technologies offer maximum herbicide program flexibility including conventional programs, the LibertyLink® system and stacks available with glyphosate resistance.

All Pioneer hybrids with Herculex traits are treated with Poncho® 250 insecticide seed treatment to help with stand establishment and seedling growth.
