Bacterial blight (Xanthomonas campestris pv. malvacearum) of cotton is an important severe disease occurring in all cotton growing areas of Pakistan. Resistance to it may be systemically induced when plant defenses are preconditioned through prior infection or treatment against subsequent challenge by the pathogen. Here, we conducted field trial to induce systemic resistance against the bacterial blight of cotton and their effect on cotton yield. The disease was artificially inoculated with 109 CFU/mL by spraying on lower surface of healthy leaves. The experiment had five plant activators as treatments which were salicylic acid, K2HPO4 , KH2PO4, citric acid and benzoic acid with three concentrations (1, 2 and 3%). Results showed that among these five plant activators, salicylic acid at 3% concentration had the best systemic acquired resistance and high yield followed by citric acid.
