Stubby-root nematode (Paratrichodorus minor) is a nematode pest. It was first detected in Louisiana in 2007.
These nematodes are of agricultural importance both as plant-pathogens and as vectors for plant viruses. They are ectoparasites that feed primarily on meristematic cells of root tips. Feeding by these nematodes can cause cessation of root elongation and an abbreviated root system termed stubby root disease. The damaged root systems have reduced capacity to extract water and nutrients from soil and predispose turf to environmental stresses. .
