New Rootworm Protection

Rootworms are crafty critters, and new biotech traits to keep this pest confused are good news. The next-generation corn rootworm trait coming out of Syngenta’s technology pipeline will be called Agrisure Duracade. The proprietary Bt technology features a novel mode of action against corn rootworm that is different from the company’s Agrisure RW trait.

The Agrisure Duracade trait, with unique protein eCry3.1Ab, binds differently in the gut of target
insects, which makes it a valuable tool in managing resistance.

Once deregulated, the trait will help deliver new seed solutions, says David Morgan, president of Syngenta Seeds Inc. The Agrisure Duracade trait will be stacked with other insect traits and not marketed as a stand-alone trait product.

"Stacking dual modes of action for the control of insects will allow us to create reduced refuge offerings that will help growers maximize yields and also prevent the development of resistant insects in their fields," Morgan says.

Syngenta petitioned for the dereg-ulation of Agrisure Duracade, also known as Event 5307, in December 2010. If approved, the new trait technology might be available in products as early as 2014.
