Stubby root nematode

Taylor Laabs

Scientific name: Trichodoridae

Body type: Stubby-root nematodes are ectoparasitic nematodes. They are characterized by having a six-layer cuticle (body covering). Stubby-root nematodes are unique among plant-parasitic nematodes because they have an onchiostyle, a curved, solid style or spear they use in feeding.

Damages: very damaging on turf grasses. By damaging the turf root system it makes the turf more prone to environmental stresses and may lead to increased use of water and fertilizer inputs.On turf grasses, damage caused by these usually occur in irregularly shaped patches within a given area. Symptoms are usually worse in sandy than in heavier soils. The turf may wilt in these areas, thin out, and die if stresses such as drought occur. Roots may appear abbreviated or "stubby" looking.  They are most attracted to turf grasses.

Nematicides are available for use on golf courses, sod farms, cemeteries, athletic fields, and industrial grounds. Often, if other turf stress factors such as improper mowing, insufficient light, and poor irrigation coverage. Damage can be lessened by improving these conditions. Increasing irrigation frequency also can help, but may not be practical during times of water restriction.

Females lay eggs that remain in soil until they hatch as second-stage juveniles. Stubby-root nematodes are obligate plant-parasites, meaning that they must feed on plants in order to survive and reproduce.


1.They got there name because they cause the roots they feed off of the look slightly "stubby"

2. You can find them practically anywhere
