This article reports that growers considering new com hybrids with stacked Bt technologies should take a closer look at insect-resistance management (IRM) requirements for 2005. Regulations accompanying these products, such as newly available Pioneer brand hybrids with the YieldGard Plus trait, incorporate compounded guidelines in the United States. Growers can meet IRM requirements through common or separate refuges. In a common refuge, the YieldGard Com Borer and YieldGard Rootworm traits in YieldGard Plus hybrids are managed as one component. The refuge must be within or adjacent to fields containing the YieldGard Plus traits.
