ABSTRACT
The search for alternative control methods against root-knot nematode disease is a reality for several researchers. Thus, the objective of the current study was to observe if filtrates from cultures of saprobic fungi from the Northeastern semiarid region, Brazil, can control Meloidogyne javanica in tomato plants. The filtrates from the culture of 10 saprophytic fungi, water (control), potato and dextrose, Pochonia chlamydosporia (standard biological treatment) and chemical treatment were used in the following experiments: hatching, mobility, J2 mortality and greenhouse trials. All studied filtrates decreased nematode hatching and caused J2 mortality. In the greenhouse experiments, the filtrate from the culture of the fungus Curvularia inaequalis decreased the number of eggs and the number of galls per root system without influencing the development of the tomato plant.
