Root-knot nematode caused by Meloidogyne incognita is the major constraints in production of tomato and other solanaceous crops. Nematode diseases have been controlled more recently by means of certain beneficial bacteria that are indigenous to the rhizosphere of plants. Among the PGPR, Bacillus spp. is very important bio-agent that has several benefits compared to other rhizobacteria. Biological control is free from residual and adverse environmental effects. Hence, biological control is gaining more importance in the recent decades. Different concentrations culture filtrates of Bacillus spp. were tested for their efficacy on egg hatching inhibition of M. incognita under in vitro conditions. All the species had significant effect on egg hatching inhibition. However, maximum suppression of egg hatching was observed in case of B. pumilus-K-1 (94.18 %), followed by B. megaterium-IIHR (92.93 %), B. subtilis-IIHR (90.43 %) and B. subtilis-P-203 (92.09 %) in 100 per cent concentration at 120 hours after treatment.
