Pot culture experiment was conducted under shade net to study the bio control potential on root knot nematode management using commercially available liquid formulation of Pseudomonas fluorescens, Paecilomyces lilacinus, Verticillium chlamydosporium. Bacillus subtilis and Trichoderma viride with standard check P. fluorescens (Pf1) (talc formulation) along with chemical check Carbofuran 3G and compared with untreated control. From this experiment it was observed that the maximum shoot length and shoot weight of bhendi was recorded 60.79% and 54.87% respectively in P. fluorescens (2ml/L) treated plants followed by V. chlamydosporium (2ml/L) compared with untreated control. Similarly P. fluorescens (2ml/L) treated plants were recorded root length and root weight of 50% and 45% respectively which was higher than that of untreated control. Regarding yield of bhendi, P. fluorescens (2ml/L) treated plants recorded maximum of 0.19 kg/plant compared to other treatments. Lowest number of root knot nematode population (151) was recorded in P. fluorescens (2ml/L) followed by V. chlamydosporium (2ml/L). The adult female nematode population was also recorded as 12 per g of root in P. fluorescens (2ml/L) and V. chlamydosporium (2ml/L) treated plants respectively. Lowest root gall index 2 was recorded in P. fluorescens (2ml/L) and V. chlamydosporium (2ml/L) treated plant compared to untreated control.
