The European Commission has given grain import approval to Syngenta’s Agrisure Duracade corn rootworm trait.
That clears the way for Syngenta to fully commercialize the Bt trait since it now has approval for import in virtually all major export markets. Hybrids containing the Duracade trait have been sold and planted in the U.S. since 2014, but have been subject to strict grain marketing requirements to ensure grain produced is funneled to domestic users. USDA approved Duracade to plant in the U.S. in 2013.
Agrisure Duracade hybrids are sold as stacked traits (Agrisure Duracade 5222 E-Z Refuge and Agrisure Duracade 5122 E-Z Refuge), and all of the individual components of these stacks are now approved.
Duracade expresses a unique protein (3Cry3.1Ab), which has not been used on the majority of corn acres. However, growers under extreme corn rootworm pressure should note that university entomologists have already documented cross resistance to the trait.
