In Alabama and other southeastern states, corn is frequently planted in rotation with cotton and peanut in order to minimize soil-borne pest problems. Even in areas where peanut is not grown, corn is increasingly being planted in rotation with cotton. However, one root-knot nematode, Meloidogyne incognita race 3, causes damage to both cotton and corn. In this study, we determined levels of corn grain loss when southern root-knot nematodes are present in soil.
