Abstract: Cabbage is one of the important cole crop grown around the world. Cabbage is susceptible to numerous diseases. However, the most destructive among them is black rot. Pathogen was isolated from leaves showing typical V- shaped lesions and identified as Xanthomonas campestris pv. campestris through morphological and biochemical characteristics. The biochemical tests showed that Xcc is small rod shaped, gram negative in gram staining and gave positive result for KOH test, starch hydrolysis test and negative for oxidase test. Pathogenicity of Xcc was confirmed according to Kotch’s postulate.
