Cowpea is important multipurpose crop which is used for the purpose of food, feed, forage, catch crop, green manuring and cover crop. The crop is prone to rust disease which causes severe yield loss. Hence to manage the disease chemicals which are expensive and hazardous are usually used by the farmers. Alternately a different strategy to manage the same was experimented with the use of elicitors which are compounds which activate chemical defence in plants and this induced defence response in susceptible variety C-152 was examined. The compounds like Salicylic acid (SA), Jasmonic Acid (JA), biocontrol agents viz., Trichoderma viridae, Pseudomonas fluorescence were used as elicitors. All elicitors were found effective in inducing resistance against rust disease by accelerating the enzyme activities like peroxidase, phenylalanine ammonia lyase and β1, 3-glucanase activity. This was higher in abiotic elicitorsthan the biotic elicitors. The highest enzyme activity of phenylalanine ammonia lyase was recorded in foliar spray of 1mM salicylic acid at 50 DAS followed by uredospores suspension after 2 days whereas, highest peroxidase and β1, 3-glucanase activity was recorded in foliar spray of 0.5mM Jasmonic acid spray at 50 DAS followed by uredospore suspension after 2 days. Hence these elicitors could be used as alternative to chemical pesticides, an important component of organic farming and integrated disease management.
