Corn rootworm populations are unusually high this year in many areas of Iowa. The snow cover for most of the 2000/2001 winter insulated the ground and contributed to the increase in rootworms in 2001. The past winter was mild, so I expected high populations of rootworms to continue or be even higher than in 2001. I began to prepare for this possibility with my article in last week's Integrated Crop Management newsletter on insecticide failures and what can be done now.
