What Are Nematodes?
Nematodes are typically tiny roundworms that thrive in virtually all environments on earth. They are the largest group of multicellular species in the animal kingdom. Some species are parasites of plants and cause economic losses in a wide variety of food, ornamental and industrial crops. Other species however are beneficial: they may help in the recycling of soil nutrients, or may feed on pathogenic fungi, bacteria, insects or other nematodes. In addition, nematodes are one of the favorite model organisms in studies on molecular genetics. This workgroup is mainly focused on developing and extending information about plant-parasitic and beneficial nematodes.

Plant Parasitic Nematode Thresholds/Damage Levels
Crop damage is typically related to the density of plant-parasitic nematodes at seeding or planting although plant response as well as soil biotic and abiotic factors may modify the crop injury extent. A Nematology Workgroup project compiled crop damage thresholds for some important nematode pests in California.
