Bacterial leaf blight of rice, caused by Xanthomonas oryzae pv. oryzae is not only a problem in India but also worldwide. Management using chemicals is undoubtedly quick in action, restricting the severity and spread of the disease. Both in vitro and in vivo studies were conducted to investigate the inhibitory potential of different chemicals against the bacterial pathogen. Out of eight chemicals comprising both antibiotics and fungicides, Streptomycin sulphate 90% + Tetracycline hydrochloride 10% exhibited highest inhibitory effect in lowest concentration of 100 ppm followed by 2-bromo-2-nitropropane 1,3-diol (15.5%). Streptomycin sulphate 90% + Tetracycline hydrochloride 10% @ 100 ppm proved best in controlling BLB in pot condition with 42.2% disease reduction and 121 % yield increase over control.
