DuPont received two U.S. Environmental Protection Agency (EPA) registrations for products that will help maximize corn yields, simplify regulatory compliance for growers and help preserve in-plant insect protection technology.

DuPont business Pioneer Hi-Bred has approval from the U.S. EPA for Optimum AcreMax and Optimum AcreMax Xtra insect protection products in corn. Optimum AcreMax marks the industry's first U.S. approval of a single-bag integrated refuge product that targets only above-ground insects. Both Optimum AcreMax and Optimum AcreMax Xtra products integrate all of a Corn Belt grower's refuge needs into a single bag.

"We are excited to offer corn growers the broadest line-up of simplified, integrated refuge products in the industry," said Paul E. Schickler, president of Pioneer. "Optimum AcreMax and Optimum AcreMax Xtra products from Pioneer will not only help growers maximize corn yields but preserve valuable in-plant insect protection for the future."

Optimum AcreMax products integrate 95 percent of a trusted, high-yielding Pioneer brand hybrid containing Herculex I insect protection combined with YieldGard Corn Borer insect protection and 5 percent of a similar non-Bt herbicide tolerant hybrid to serve as the integrated corn borer refuge.

Optimum AcreMax Xtra products integrate 90 percent of a trusted, high-yielding Pioneer brand hybrid containing Herculex XTRA insect protection combined with YieldGard Corn Borer insect protection and 10 percent of a similar non-Bt herbicide tolerant hybrid to serve as the integrated corn borer and corn rootworm refuge. Optimum AcreMax and Optimum AcreMax Xtra products offer built-in refuge compliance in the Corn Belt.

Pioneer will conduct a commercial launch of Optimum AcreMax and Optimum AcreMax Xtra products across multiple hybrid platforms for the 2012 selling season.

"Our business approach is to work closely with growers to understand their individual needs and help maximize productivity by placing the right product on each acre," said Schickler. "Optimum AcreMax and Optimum AcreMax Xtra products further expand our offerings of new insect protection control solutions to benefit U.S. corn growers and deliver on that commitment."

• Optimum AcreMax 1 insect protection - the industry's first integrated corn rootworm refuge solution.
