The incidence of bacterial leaf blight of coriander were surveyed from January 2002 to December 2002. The disease was found from June to October, but the highest incidence occurred from July to September. The causal agent of the disease, Xanthomonas campestris pv. coriandri, could not survive when immersed in 50 degrees C hot water for 30 min., but coriander seed germination rate was not affected with the same treatment. The seed germination rate decreased significantly when water temperature was raised to 55 and 60 degrees C. Field trials showed that 27.12% Tribasic copper sulfate F.P., 56% Cuprous oxide W.P., 77.5% Kasugamycin + Copper oxychloride W.P. and 77% Cupric hydroxide W.P. 25% were effective to control the disease.
