Diagnosis and Management of Bacterial Plant Diseases

  • B. S. Thind


For an effective disease management, the correct diagnosis of a disease based on the identification of its causal agent is very essential. The diagnosis of some diseases on the basis of symptoms can be made to a satisfactory level, but the identification of the causal agent is necessary for confirmation. For the diagnosis of a plant disease, a comprehensive host list that covers a known disease, its typical symptoms and its known potential pathogens for a specific host is required. The compendia of different crop diseases published by American Phytopathological Society are very valuable publications for this purpose. A list of plant diseases found on the website ( of American Phytopathological Society is also a source of valuable information. Westcott’s Plant Disease Handbook is also useful because specific symptoms associated with each disease are given (Horst, 2001). The photographs of symptoms, especially the coloured ones, also aid in the identification of plant diseases. A list of known pathogens for a given crop greatly reduces the choices to one or two suspected genera for the given symptoms.
