The species Meloidogyne javanica (Treub)
Chiwood is taken into account as one of the dangerous
species of this genus causing the economic damages in the
world and Iran also (Akhiani et al. 1984). Because of the
importance of economic damages by this nematode, great
efforts have been carried out to manage it including bio-
logical control practices and in the last decades, researchers
have tried to manage the nematode populations using
organic fertilizers (Addabdo 1995).
