Most farmers are tickled to get single-bag RIB (refuge in bag) for 2012. It eliminates the hassle of planting a refuge and any worries of compliance.

The latest integrated product comes from Monsanto Company. This option is specifically designed for farmers who do not experience corn rootworm pressure in their fields.

Genuity VT Double Pro RIB Complete is a blend of 95% Genuity VT Double Pro and 5% refuge (non-Bt) seed incorporated in a single bag. The product will be offered by Monsanto brands and licensees across the central Corn Belt. Because of Bt use in cotton, Southern corn growers do not have RIB products available.

Genuity VT Double Pro with a structured 5% refuge was initially introduced in 2010. It contains two modes of action to protect against aboveground insects such as European corn borer, southwestern corn borer, fall armyworm and corn earworm, and it exhibits tolerance to Roundup herbicide applications.

Matt Kirkpatrick, Monsanto corn traits marketing manager, says all Genuity VT Double Pro hybrids in Monsanto brands will be fully converted to a RIB product for 2012 at no additional cost to growers. "Availability should be good, and growers will find hybrids available in the 80- to 120-day maturity range," Kirkpatrick says.

He notes that winter production is also playing an important part in seed production for 2012. "So far, our winter seed production looks good and, in fact, was planted a week to a week and a half earlier than normal," Kirkpatrick says.

Convenience and guaranteed compliance are two examples of the advantages of the RIB system.
However, Kirkpatrick says, farmers shouldn’t overlook the trait’s ability to fend off tough-to-control insects, especially corn earworm. "Just three damaged kernels per ear can translate into a yield loss of 1 bu. per acre. In most cases, corn earworms don’t stop at three kernels," he adds.
