Both the Southern root-knot and reniform nematodes are often found together in the mid-South and Southeast areas of the United States. Site-specific management plans need to factor in both populations of the two nematodes and changes that will occur when rotation crops are utilized. Fields that have variability in soil texture often have areas that are more suited for each of the two nematodes. The Southern root-knot nematode is usually restricted to the lighter soil textures within a field while reniform seems to be more widespread and often occurs in fairly heavy soils. The use of rotational crops such as corn may drastically impact populations of the reniform nematode but maintain damaging populations of the Southern root-knot. The objectives of this study were to look at two fields infested with both the Southern root-knot and reniform nematodes and make predictions about the impact of one or two years rotation with corn. Since populations of the reniform nematode will decline with the use of corn, the heavier soil zones should be less impacted and not require treatment with a fumigant. Since corn would not reduce the Southern root-knot nematode, the lighter soil areas dominated by this nematode would still need treatment. [ABSTRACT FROM AUTHOR] |
