Induction of systemic resistance by rhizobacteria for the management of root-knot nematodes in tomato
Pseudomonas fluorescence and Bacillus subtilis as Plant Growth Promoting Rhizobacteria (PGPR) isolated from root rhizosphere of tomato plant were utilized for growth promotion and induction of systemic resistance in tomato against root knot nematodes. Present study was aimed to study the ability of two rhizobacterial isolates i.e., Pseudomonas fluorescence and Bacillus subtilis to induce systemic resistance and their effect on growth promotion The influence of rhizobacteria Pseudomonas fluorescence and Bacillus subtilis on growth parameters of the tomato plant and mortality of nematodes was studied in growth chamber and in net house conditions. More increase was observed in case of Pseudomonas fluorescence and results elucidated an increase in plant height (12.4％), fresh weight of shoot (45.6％), dry weight of shoot (37.03％), fresh weight of root (68.75％) and dry weight of root (114.28％) in growth chamber in case of Pseudomonas fluorescence while in net house plant height was observed to be increased by 25.6％, 66.66％ increase in fresh weight of shoot, fresh weight of root and dry weight of root were also increase by 47.6％ and 40％ respectively while 7％ decrease was observed in dry weight of shoot.
