Chemical inducers facilitate broad-spectrum of induced resistance against plant pathogens and thus reduced the toxicity of the chemicals used in excess by the farmers for the management of plant diseases. Banana soft rot incited by Pectobacterium carotovorum subsp. Carotovorum (Pcc) cause huge economical loss to the farming if infected at an early stage. In the present study, chemical inducers viz., salicylic acid, potassium silicate, potassium sulphate, fosetyl aluminium, humic acid @ 1000 ppm and COC 3g/lit + streptocycline 300ppm (check) were tested against Pccunder glass house conditions. The results revealed that salicylic acid @ 1000 ppm effectively reduced the soft rot disease incidence (58.33 % disease reduction over inoculated control) and it was followed by potassium silicate (50 %) and fosetyl aluminium (45.83 %). Besides, chemical inducers induced defense enzymes viz., PO, PPO, PAL, SOD and phenols on 5thday after inoculation in addition to plant growth promotion. Thus, it is concluded that resistance is induced in banana by chemical inducers and play a major role in the management of banana soft rot disease.
