Alternaria leaf blight being a major concern on mustard whose control largely depends on the application of chemical pesticides however it is not the long term solution due to environment concern and risk due to fungicide residues. Under these circumstances, Induced resistance is one of the most dominant mechanism in managing the disease by increasing the activity of various defense related enzymes and non-enzymatic antioxidants. Role of inducers viz. Benzothiadiazole (BTH), Salicyclic acid (SA), Jasmonic acid (JA) and Hydrogen peroxide (H2O2) at three different concentrations viz. low, medium and high concentrations, viz. BTH (0.25 mM, 0.75 mM, 1.5 Mm); H2O2 (1%, 2%, 3%); JA (1mM, 2.5 mM, 4 mM) & SA (0.5 mM, 1 mM, 2 mM) were evaluated on induction of resistance to manage Alternaria blight of mustard in three different varieties viz. resistant, moderately resistant and susceptible against the disease was studied in net house. Elicitor treatments exhibited maximum content of chlorophyll

The studies in this area may provide information concerning host-pathogen interaction which can be utilized for resistance breeding and thus desirable trait can be developed by incorporating resistance in promising but susceptible genotype of mustard. 2) Study of factors responsible for triggering of defense genes through signal transduction which are stimulated by elicitors should be studied at gene level. 3) There is need to search for various inducers responsible for inducting resistance should be studied through enzyme markers. 4) The efficiency of various elicitors in field level should be assessed on various genotypes of the crop and there performance can be evaluated by using resistance markers. 5) Effort should be made such that, elicitors should be commercialized by recommending as seed treatment in farmer’s field which may become an alternative to chemical fungicides in management of few disease where fungicide resistance was established by pathogens is a major proble
