Plant growth-promoting rhizo-bacteria play a vital role in the suppression of plant diseases. Pseudomonads are well known to show the growth promotion activity in plants and simultaneously activating the disease incidence delay. Promising strains of Pseudomonas  isolated from different soil samples collected from various geographical regions of central Himalayas were applied as seed bio priming (SB), SB+ Root Dip (RD), SB+RD+ Drenching (DR) and SB+RD+DR+ Spraying (SPR) individually and in combination with different strains and evaluated for their effect on management of early blight caused by Alternaria solani an important disease of tomato. Disease incidence was reduced by the application of bio-inoculants individually as well as in combinations. The minimum disease incidence was recorded when different strains as consortia were applied as SB+RD+DR+ SPR.

Key words: Alternaria solani, Rhizo-bacteria, Pseudomonads, Plant growth promotion
