Some grub activity in corn has been noted this growing season. Ideally, scouting for true white grubs should occur prior to planting, however, most people do not realize they have an infestation until stand loss occurs. Areas that were previously pasture or sewn to grass should be monitored for their presence. Grubs are more likely to be found in fields close to cottonwood or willow trees. In some instances, the presence of true white grubs within field crops is not well understood.
