Nematode resistant peanut cultivars are not a viable control option open to Alabama peanut farmers. Severe nematode injury will also break the resistance of this peanut cultivar to white mold. Nematode overwinters in soil as an egg or second stage juvenile. Juvenile can move several feet up through soil profile and then penetrate into pegs, pods, and roots. Feeding in roots triggers an increase in cell size and number which leads to gall formation.
Adults are sedentary in roots.
Lesion Common nematode but is not as damaging to peanut as peanut root-knot. Juveniles and adults survive in peanut debris in soil. They will move into and feed on all belowground parts of peanut plant but are most numerous in pods. They also appear on pods as small, discolored spots or speckles. Ring Common nematode can cause sizeable yield loss but not as destructive as peanut root-knot.
