EFFECT OF CULTURE FILTRATES OF PAECILOMYCES LILACINUS ON MELOIDOGYNE JAVANICA

F. A. Zaki

Abstract


Laboratory experiments showed that fungal filtrates of Paecilomyces lilacinus inhibited the hatching of Meloidogyne javanica at all the concentrations used when exposed for72 hours, which, however, resumed partially in water. Irreversible inhibition ranged from 47 to 62 per cent. The fungal filtrates immobilized second-stage juveniles, more, in higher concentrations. Activity of filtrates obtained from the buffered medium was stronger than that from unbuffered medium. However, activity of J2 resumed in all the cases after 24 h exposure.
