Herculex RW Receives U.S. Regulatory Approvals

Indianapolis and Des Moines, Iowa (October 5, 2005) – Corn growers who have been fighting corn rootworms can now protect their corn with the Herculex® RW Rootworm Protection trait in 2006.

 

Dow AgroSciences LLC, a wholly owned subsidiary of The Dow Chemical Company (NYSE: DOW), and Pioneer Hi-Bred International, Inc., a DuPont business (NYSE: DD), the trait's developers, recently received confirmation that Herculex RW has received full food and feed approvals within the United States.

Herculex RW has received registration by the Environmental Protection Agency (EPA) and deregulated status from the United States Department of Agriculture (USDA) and successfully completed the consultation process with the Food and Drug Administration (FDA). Dow AgroSciences and Pioneer are also seeking registrations in Canada and other countries as well as grain import approvals for key export markets, such as Japan.

"Herculex RW will give farmers built-in protection against corn rootworm, the costliest insect pest in corn," says Wally Thingelstad, marketing specialist, Traits Licensing, at Dow AgroSciences. "More importantly, Herculex RW will give corn growers several outstanding hybrid options when choosing corn rootworm protection."

"This is great news for our customers," says Paula Davis, senior marketing manager, insect and disease traits, Pioneer. "Many growers have faced increased pressure from corn rootworm in recent years, finding that traditional methods, such as crop rotation, are no longer effective. Herculex RW offers an excellent protection option within the seed itself for ease and efficiency."

Herculex® RW Rootworm Protection will provide a high level of protection all season long against western, northern and Mexican larval corn rootworm. The trait will be available in hybrids for the 2006 season from Mycogen Seeds, Pioneer and Beck's Superior Hybrids, Inc.

"Herculex RW has performed very well in field trials," says Jon Babcock, senior research scientist at Dow AgroSciences. "It outperformed granular insecticides and high-rate seed treatments and provided consistent protection in light to heavy rootworm pressure and in wet or dry conditions."

"Our field trials have shown that Herculex RW provides excellent root protection and a dramatically lower number of adults emerging from the field," says Murt McLeod, agronomy sciences research manager for Pioneer.

All Herculex traits have LibertyLink® technology providing tolerance to LIBERTY® herbicide which controls more than 100 grass and broadleaf weed species on contact.

Dow AgroSciences and Pioneer also anticipate EPA registration of Herculex® XTRA Insect Protection in the near future. Herculex XTRA will combine the corn rootworm protection of Herculex RW with the broad insect protection of Herculex I Insect Protection - protection against corn borer, black cutworm, western bean cutworm and other destructive pests - to give corn growers the broadest-spectrum in-plant insect protection available.
