Induced resistance in bhendi against powderymildew by foliar application of salicylic acid

ABSTRACT The effect of salicylic acid in inducing systemic resistance in bhendi against powdery mildew caused by Erysiphe cichoracearum DC was investigated by the application of salicylic acid (1mM) to induce production of defense related enzymes and chemicals in plants when it was applied as pre-inoculation, post-inoculation, salicylic acid alone, pathogen alone and water control. The results revealed that earlier and increased activities of phenyl alanine ammonia lyase, was observed in salicylic acid pretreated bhendi plants challenge inoculated with E.cichoracearum. Higher accumulation of phenolics was also noticed in plants pretreated with salicylic acid and able to enhance the resistance against invasion of E. cichoracearum in bhendi
