The preventive activity of organic elicitors viz. salicylic acid (SA) and jasmonic acid (JA) to control post-harvest infection of green mold (GM) and blue mold (BM) on Citrus reticulata cv. kinnow, C. limon cv. meyer lemon, and C. limetta cv. mosambi was evaluated in a dose-responsive study. SA and JA reduced the disease severity and incidence as compared to infected control. Both organic elicitors showed significant reduction of disease severity, while, the reduction in disease incidence was not significant on all the fruits. SA showed thea slightly better reduction in disease severity than JA. The efficacy of both elicitors was concentration-dependent with a higher reduction in disease development at higher concentrations. To get an insight into the mechanisms underlying the increased resistance, the activity of defense-related enzymes, peroxidase (POD) and polyphenol oxidase (PPO) waswere recorded in organic elicitorselicitor treated fruit peels. The activity of both enzymes was significantly increased in parallel towith increase in disease resistance in a concentration-dependent manner. This study is significant in the manner of disease resistance due to increased activity of PPO and POD in SA and JA treated citrus fruits.
