A host for the nematode(s) of interest is planted, allowed to grow for a time, and killed prior to the development of egg bearing adults.
It is important to destroy the roots of the crop so they do not continue to support nematode development. The technique is not useful for migratory ectoparasitic or endoparasitic nematodes because the juveniles and adults are able to move to other roots and continue to feed and develop.
