Full, three-fourths, and one-half rates of Force 3G insecticide were applied in-furrow at planting time on both continuous corn and rotated (corn/soybeans) cropping schemes. It was thought that northern corn rootworms, with extended diapause capabilities, may have caused damage to first-year corn in 2001.
