Damage to Turf. Ring
nematode damage to turf usually occurs only at high populations. Most
common on golf course greens.
Biology. The ring nematode is an ectoparasitic
nematode and feeds on interior portions of the roots but is found in the
soil outside of the root. Criconematinae are markedly annulate stubby nematodes,
ranging from 0.2 - 1.0 mm in length.
Ecology. Large populations usually occur
only in highly sandy soil.
Symptoms. Yellowing, moisture-stress wilting and poor
growth in above-ground foliage.
Damage to other crops. Peanuts are also
a host of ring nematode.
