The aim of this work was to study the Induced systemic resistance and their implications in host resistance to physic nut against leaf blight disease. In pot culture experiment plant treated with Mancozeb (0.2%) and Propiconazole (0.1%) thrice starting from 30 days after planting with an interval of 15 days was significantly superior over all the treatments with the PDI of 18.44 and 19.00 respectively. The plant height was significantly increased in all treated plants ranging from 99.80 cm to 148.25 cm. Plants treated with Pseudomonas fluorescens (Pf1) induces more phenyl alanine ammonia lyase (PAL), peroxidise (PO)¸ poly phenoloxidase (PPO), β-1,3 glucanase, super oxide dismutase (SOD) and phenol activity in treated physic nut plant followed by Bacillus EPCO16 treated plants.
