Pratylenchus crenatus Loof, 1960

Morphology and Anatomy:

Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Economic Importance:

D-rated pest in California Nematode Pest Rating System.

Feeding:

    Migratory endoparasite.

Population levels of P. crenatus increased at different rates on wheat, maize, buckwheat, common rape, common persicaria, common agrimony, horseweed and soaproot. The best host was horseweed and the worst was wheat. Body size parameters of the nematode differed among hosts (Urek, 1999).

Turf (golf courses) in Ontario, Canada. Also from fruit trees in Canada (Yu, 2008).

Tobacco in Japan.

Corn.
