ABSTRACT:

Biocontrol agents viz., Paecilomyces lilacinus, Trichoderma harzianum, Asprgillus niger and Glomus fasiculatum (VAM fungus) at four different concentrations were used for the management of Meloidogyne incognitaroot-knot nematode. All bio-control agents were found effective for the control of root-knot nematode, but a better performance was noted in VAM fungus (50 chlaymydospores) followed by P. lilacinus (5000 spores), T. harzianum(5000 spores) and A. niger (5000 pores). Higher growth parameters and maximum amount of yield and root nodules were recorded in VAM fungus. Maximum reduction of root-knot infection was recorded in P.lilacinus. Higher number of total rhizosphere bacteria (Rhizobium and Azotobacter) were recorded in soil amended with VAM fungus. Reduction of fungal colonies and plant parasitic nematodes were recorded from rhizosphere of plant
grown in T. harzianum and VAM fungus, respectively
