Plant growth promoting rhizobacteria (PGPR) are known to enhance growth and vigor of various plant species specially leguminous pulse crop plants. Application of Pseudomonas sp. and Bacillus sp. significantly reduced infectivity rate of Meloidogyne incognita on Vigna mungo. Growth parameters in terms of shoot length, root length, shoot fresh and dry weights, root fresh and dry weights and number of nodules per plant were found significantly increased in the plants treated with the two bacteria as compared to control. Maximum inhibition of root knots (42.79 per plant) was observed in plants inoculated with M. incognita and simultaneously treated with 20 ml of Pseudomonas fluorescens and Bacillus subtilis.
