Nematode detection and identification requires the services of a professional nematologist. Identification of nematode species level is essential prerequisite for a control tactics. However, identification is difficult because there are few morphological characteristics of taxonomic value for rapidly and accurately differentiating many genera of nematodes. Diagnostic labs therefore usually identify parasitic nematodes only to the genus level and do not differentiate species as a regular component of the testing service. Molecular procedures using a single DNA extract from soil will soon be available to precisely differentiate and quantify individual species of plant parasitic nematodes.
