In vitro screening of indigenous isolates of Bacillus spp., against Meloidogyne incognita and Fusarium oxysporum f.sp. lycopersici

Ten different indigenous isolates of endophytic Bacillus spp. collected from tomato and chilli grown in Tamil Nadu, India were screened in vitro for their influence on M. incognita and Fusarium oxysporum f.sp.lycopersici. All the isolates had effect to inhibit egg hatching and to cause mortality of juveniles of M.incognita, to arrest mycelial growth and development of Fusarium oxysporum f.sp.lycopersici and thereby proved their antinemic and antifungal property. The antimicrobial effect of culture filtrates of different ten isolates of Bacillus spp. showed positive correlation with their concentration and time of exposure. Among the ten isolates, B. weihenstephanensis (TSB4) is ranking first and it was followed by B. cereus (CLB2D), B.licheniformis (TSB3), B. weihenstephanensis (CLB3), B.tequilensis (TLB2) and B. cereus (CLB2) in this regard
