Hoplolaimus galeatus
The Lance Nematode
-
Damage to Turf. Hoplolaimus
galeatus damages turf at low populations. It is found primarily
on greens and tees.
-
Biology. Hoplolaimus
species are rather stout, large nematodes, with stylet
knobs projecting forward. Lance nematodes migrate through the
soil along roots, feeding as they move.
-
Ecology. Lance nematodes are widely distributed
in the United States, but large populations are found only in sandy or
well-drained soils.
-
Symptoms. Common symptoms of nematode
injury to turf are slight to severe yellowing of the foliage, thinning
of the turf canopy, reduced growth, wilting under light moisture stress,
and premature death.
-
Damage to other crops. The lance nematode
has a wide host range, and has been shown to parasitize many types of
plants.
-
Control. Chemical control using fumigants has been
effective.
