Symptoms are the result of nematodes feeding on roots by sucking out the con tents of cells.
They seldom kill their host. Plant resistant varieties, rotate annual crops, and leave infested areas fallow and solarize over the summer. Nematodes move slowly through the soil, and may be moved to a new location with a transplanted plant or by garden tools.
