Abstract

Four years studies (1999-2002) on more than 100 cultivated medicinal plant species and their soil specimens to identify and examine population dynamics of medicinal plants' parasitic nematodes in Isfahan province revealed the presence of several plant parasitic nematodes in the rhizosphere. The nematode genus present in Dastgerd station belong to the following genus: Helicotylenchus, Meloidogyne, Goeocenamus, Longidorus, Ditylenchus, Tylenchus, Criconemella, Xiphinema, Psilenchus, Pratylenchus on the basis of population density respectively. Whereas in Kashan station, Tylenchus, Xiphinema, Helicotylenchus, Meloidogyne, Geocenamus and in Najafabad station, Meloidogyne, Helicotylenchus, Geocenamus, Ditylenchus, Xiphinema, Tylenchus, Criconemella, Pratylenchus, Aphelenchus, Psilenchus and in Mobarakeh station Criconemella, Longidorus, Xiphinema, Meloidogyne, Tylenchus, Helicotylenchus, Geocenamus had the most densities in mentioned stations respectively. The following species were identified as parasitic nematodes in the studied areas: X. index, X. pachtiacum, X. vuittenezi, L. africanus, H. pseudorobustus, H. digonicus, H. vulgaris, M. javanica, M. incognita, G. brevidens, G. microdorus, G. rugosus, Criconemella antipolitana, C. xenoplax, Psilenchus hilarulus, Ditylenchus dipsaci, D. destructor, D. acutus, Pratylenchus neglectus, P. penetrans, P. thornei and P. minyus.
