Continuous Corn Production
Managing Corn Rootworm
Even before the advent of genetic insect control, this pest has been difficult to control. Insecticides applied with the planter to combat feeding larvae can demonstrate control, but weather can cause failures. Either too much rain can dilute the insecticide or move it out of the root zone, or lack of rain can reduce effectiveness and limit the zone of control. In either case, survival of larvae feeding on roots can cause economic damage.
