EPA approves Syngenta CRW insect trait stack

Syngenta announced Thursday that the U.S. 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, Agrisure 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.

This registration follows the first EPA approval for the corn rootworm resistant trait in October 2006. The stacks will be available to U.S. growers in various combinations through 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 seed brands through its GreenLeaf Genetics joint venture. U.S. Department of Agriculture authorization to ship the double-stack trait is expected for the 2007 growing season.
