NEMATODES IN TURF

摘要

If you have ever seen damage on turf that doesn't fit in with the symptoms of disease, animal or insect attack, then you may have experienced the effects of a nematode infestation. Nematodes are round worms that belong to the phylum Nematoda - the second largest group of invertebrate animals after the Arthropods (Insects and bugs). Over 80,000 species of nematodes have been described but scientists believe the total number of species on this planet exceeds one million! They occur in a wide variety of habitats existing as both free-living and parasitic species. This article will concentrate on the plant parasitic nematodes that affect amenity turf.
