A pot study was conducted to evaluate the compatibility and efficacy of Pochonia chlamydosporia, Purpureocillium lilacinus, Trichoderma asperellum and Pseudomonas fluorescens for the management of root knot nematode, infecting cucumber under glasshouse conditions. The growth of fungal and bacterial biocontrol agents were not suppressed by humic acid in all concentrations tested. Humic acid inhibited the growth of the P. lilacinum, due to alkaline pH when the pH was altered from alkaline to acid condition, the growth of P. lilacinum was not inhibited. Among the bicontrol agents with humic acid tested for the management of nematodes, P. chlamydosporia showed best results in terms of plant growth parameters, reduce root knot diseases and nematode multiplication by 53% compared to control in cucumber.
