An experiment was carried out to study the interaction of root knot nematode, Meloidogyne incognita, Paecilomyces lilacinus, Pochonia chlamydosporia, Trichoderma viride, Bacillus subtilis and Pseudomonas fluorescence on the growth of black gram. This study was done to investigate the role of some bacterial genera as biocontrol agent against Meloidogyne incognita. Paecilomyces lilacinus significantly increased the growth parameters of the black gram viz., plant height, root length, fresh and dry weight of shoot and roots with significant decrease in the number of galls and final nematode population. Pochionia chlamydosporia was also noted to be superior and took second rank in improving the plant growth and reduced nematode population. Maximum plant height (19.02 cm) was recorded with Paecilomyces lilacinus followed by Pochonia chlamydosporia (17.70 cm), Trichoderma viride (16.46 cm), Bacillus subtilis (15.68 cm) and Pseudomonas fluorescence (13.96 cm). Inoculated control recorded minimum (11.10 cm) plant height. Similarly maximum (18.38 cm) root length was noted with P. lilacinus and minimum (11.24 cm) with control rest of the treatments were significantly superior over control.
