Herculex® XTRA Insect Protection

Herculex® XTRA (HXX) insect protection offers a complete spectrum of in-plant above- and below- ground insect control, by combining the Herculex I and Herculex RW traits. Herculex XTRA provides consistent, season-long control of corn rootworms. Herculex I and Herculex XTRA also provide in-plant protection against western bean cutworm and black cutworm.

All Pioneer hybrids with Herculex XTRA come standard with Cruiser Extreme® 250 insecticide seed treatment to help with stand establishment and seedling growth. High-rate Poncho® 1250 insecticide seed treatment is also an available option on many Pioneer hybrids.
