Abstract


Paecilomyces lilacinus, Phoma herbarum and three isolates of Fusarium oxysporum differed significantly in their ability to parasitize eggs and females of Meloidogyne javanica. P. lilacinus and F. oxysporum-1 significantly (P 05) parasitized more than 70% of eggs and females while F. oxysporum-3 parasitized less than 20%. Also, P. lilacinus and F. oxysporum-1 had the greatest suppressive effect on hatching. In general, control Petri-dishes and those treated with F. oxysporum-3 had the highest proportions of hatched eggs, but exhibited the least levels of egg parasitism. The fungus P. lilacinus significantly (P 0.05) parasitized eggs of M. javanica, M. incognita and M. arenaria but no significant differences were detected in the levels of parasitism.
