Syngenta announced that the EPA has approved the Agrisure Duracade™ 5122, E-Z Refuge® and Agrisure Duracade 5222, E-Z Refuge trait stacks. These single-bag refuge products will provide growers with unmatched corn rootworm protection plus a convenient 5 percent integrated refuge.

The Agrisure Duracade 5122, E-Z Refuge product combines the Agrisure Duracade trait with the trusted Agrisure® RW trait for dual modes of action against corn rootworm. This single-bag refuge product also contains the Agrisure CB/LL trait for corn borer control, the Herculex® I trait for an additional mode of action against corn borer plus broad lepidopteran control, and the Agrisure GT trait for glyphosate tolerance. It is conveniently packaged in a 5 percent integrated refuge.

Agrisure Duracade 5222, E-Z Refuge contains all of the same traits found in the Agrisure Duracade 5122, E-Z Refuge product plus the Agrisure Viptera® trait for breakthrough control of the multi-pest complex, a collection of highly destructive lepidopteran corn pests. It is also conveniently packaged in a 5 percent integrated refuge.

The Agrisure Duracade trait expresses a unique engineered protein (eCry3.1Ab) that protects against Western corn rootworm, Northern corn rootworm and Mexican corn rootworm. Syngenta and university research trials have shown the Agrisure Duracade trait is highly effective in controlling corn rootworm. Research by the US Department of Agriculture reports that the trait has the highest reduction in beetle emergence (99.79 percent) of any commercial CRW trait.*
