Defend Against Yield-Robbing Insects

Above- and below-ground insects can reduce crop health and rob bushels from your bins. The right insect protection helps maximize your crop performance.

Defend Against Yield-Robbing Insects

Defend Against Yield-Robbing Insects

Optimum® Intrasect® hybrids are locally developed to perform in a wide range of environments and combine two proven and trusted traits, Herculex® I insect protection and YieldGard® Corn Borer, to give your crop dual-mode above-ground insect protection. These hybrids provide another choice to maximize yield and preserve valuable Bt technology, with either a structured 5 percent refuge in the Corn Belt or 20 percent refuge required in EPA-designated cotton counties.

Optimum® Leptra® Hybrids

Optimum® Leptra® Hybrids

Optimum® Leptra® hybrids have a powerful pyramid of traits with three modes of action to provide superior control of above-ground pests, including corn borer, corn earworm and fall armywormon on your acres. The pyramid of traits in Optimum Leptra includes Herculex® I insect protection, Agrisure Viptera® and YieldGard® Corn Borer to deliver cleaner ears with less kernel damage through reduced ear feeding by these harmful pests. Optimum Leptra requires a structured refuge of 5 percent in the Corn Belt and 20 percent in EPA-designated cotton counties.

Herculex® Insect Protection

Herculex® Insect Protection

Herculex® insect protection offers leading protection against corn insects for maximum yield potential. Herculex I provides the same consistent control of above-ground insects for areas with minimal rootworm pressure. Herculex RW offers a high level of protection against northern, western and Mexican corn rootworm to safeguard the entire root system. Herculex XTRA is the stack of Herculex I and Herculex RW, and gives you season-long control for a broad spectrum of above- and below-ground insects. Advanced corn trait technology, such as the Optimum® AcreMax® family is built on the Herculex traits.

Glufosinate Tolerance

Glufosinate Tolerance

Pioneer® brand corn hybrids with the LibertyLink® gene provide in-plant resistance to Ignite®, a nonselective, postemergence herbicide that offers relatively quick contact action on many tough grass and broadleaf weeds.

To protect the usefulness and availability of these technologies for the future, growers must implement an Insect Resistance management (IRM) program as specificed in product use guides.

For detailed IRM requirements for product with in-plant insect resistance, refer to the appropriate product use guide, available from your Pioneer sales professional or on the web at www.pioneer.com/us/stewardship
