Corn growers are increasingly adopting the corn biotech traits in YieldGard®, Herculex®, and Agrisure® for yield protection against corn rootworms and/or European corn borers in what we call Bt corn hybrids. All of these traits require that corn growers follow Insect Resistance Management (IRM) requirements to effectively manage this technology. Surprisingly, I heard numerous corn growers during my recent winter meeting circuit around the state scoff at the IRM requirements. I'm sure many of them were thinking, is a Bt corn refuge really necessary?
