Mortality of Meloidogyne javanica larvae was directly proportional to the concentration of culture filtrates of all tested fungi viz., Verticillium chlamydosporium, Paecilomyces lilacinus and Talaromyces flavus and the duration of exposure. Maximum mortality of larvae was observed in higher concentration of P. lilacinus (82%) followed by V. chlamydosporium (66%). Similarly different dilutions of culture filtrates significantly inhibited hatching of M. javanica eggs. Larval emergence was, however, inversely proportional to filtrate concentrations. Significant lower hatching was observed with P. lilacinus (7%) followed by V. chlamydosporium (15%) in 'S' concentrations.
