New corn rootworm trait from Syngenta

Syngenta’s next-generation corn rootworm trait earlier known as Event 5307 is now called Agrisure Duracade. Syngenta started the regulatory approval process for the newly named trait a year ago but doesn’t expect to bring the trait to the market until 2014.

The Duracade trait features a “novel” mode of action against corn rootworm compared to the Agrisure RW trait currently on the market, Syngenta reports. The new trait expresses a unique protein (eCry3.1Ab) that binds differently in the gut of the corn rootworm. As a result, products with a dual mode of action may be used against the pest.

“Stacking dual modes of action for the control of destructive insects like corn rootworm will allow us to create reduced refuge offerings that will help growers maximize yields while also helping to prevent the development of resistant insects in their fields,” reports David Morgan, president of Syngenta Seeds, Inc.
