The nematicidal effect of Purpureocillium lilacium, Pochonia chlamydosporia, Pseudomonas fluorescens singly or in combination were tested against root-knot nematodes under open field conditions. In the present study, the efficacy of four biocontrol agents was tested against Meloidogyne spp. The results revealed that soil application of vermicompost @2.5 tons/ha enriched with P. lilacinum @ 2.5 kg + vermicompost @ 2.5 tons of /ha enriched with P. fluorescens @ 2.5 kg/ha (T4) proved effective to manage root-knot nematode, Meloidogyne spp. and hence increased bitter gourd fruit yield as compared to other treatments. The experiment proved that application of different biocontrol agents (P. lilacinum and P. chlamydosporia and P.fluorescens) not only has a lethal effect on nematode, but also enhances the plant growth, supplying many nutritional elements and induce the systemic resistance in plants. Through this investigation we could standardize a strategy for the sustainable management of nematode in bitter gourd.
