Corn rootworm feeding should be mostly completed by mid-June throughout north central Kansas. Thus, if there is any lodging or goose necking caused by corn rootworms, it should be showing up in the next week or two. In-furrow planting time insecticide applications still seem to work really well, as do Bt corn rootworm varieties. Crop rotation and adult management also work exceedingly well.
