Syngenta corn rootworm insect trait stack approved by US EPA

Basel, Switzerland, January 25, 2007 - Syngenta announced today that the US Environmental Protection Agency (EPA) has approved the stacked combination of its new corn rootworm trait with its European corn borer trait. This approval also enables Syngenta to launch its triple stacked corn that includes glyphosate tolerance. The double stack, AgrisureTM CB/RW, will be available in limited quantities for the 2007 growing season and the triple stack, Agrisure GT/CB/RW will be available for 2008.

“The approval of the stacked insect traits marks another milestone in our strategy to offer a highly competitive portfolio of proprietary biotech products to growers in the world’s largest corn market,” says Mike Mack, Chief Operating Officer of Syngenta Seeds. “As we scale up hybrid production over the next two seasons, this will enable Syngenta to drive growth and market share into the next decade.”

This registration follows the first EPA approval for the corn rootworm resistant trait in October 2006. The stacks will be available to US growers in various combinations through elite hybrids from Garst®, Golden Harvest® and NK® in addition to single trait offerings. Syngenta also plans to offer the single and stacked traits for use in other leading seed brands through its GreenLeaf Genetics joint venture. USDA authorization to ship the double stack trait is expected for the 2007 growing season.
