Evaluation of bacterial formulations as potential biocontrol agents against the southern root-knot nematode, Meloidogyne incognita

Abstract Background Bacterial bioagents, Pseudomonas fluorescens , P. putida Bacillus amyloliquifaciens and B. megaterium have management potential against root-knot nematode (RKN), Meloidogyne incognita in bottle gourd. Results Field laboratory experiments were conducted to evaluate the effect of bacterial bioagents 1% WP (2 × 10 6 CFU/g), 8 9 CFU/g) on egg hatching juvenile mortality nematode, M. . All species inhibited caused mortality. The lowest mean 120 h. after treatment was observed (20.9% hatching), followed by (21.1%), (23.7%), (24.7%) at 4% concentration formulated product (47%) control. found highest (57.1% mortality) exposure, (56.13%), (54.46%), (53.13%) 0.46 control, where distilled water used. Under field conditions, gourd seeds that treated either with amyloliquefaciens or g/kg seed along application neem cake (1t/ha) significantly resulted reduced root gall index number juveniles soil roots than non-treated Conclusion This study revealed tested namely amyloquefaciens showed for controlling knot (RKN) as well conditions
