| Abstract:
Amongst the different delivery methods, combination of all the five methods (seed treatment method + soil application method + nursery bed method + foliar spray method + root dip method) was found to be the best method of inoculation of Pseudomonas gladioli B25. It controlled the early blight disease by 60.2 per cent which was on par with that of the chemical control (62.5%). The strain triggered defense molecules against Alternaria solani and, thus, induced systemic resistance. The combined treatment method recorded the highest phenol accumulation, peroxidase activity and PALase activity. | |
