A new bacterial disease of bellflower was found in Mie Prefecture, Japan, in the autumn of 1997. Brown spots on leaf blades and necrotic stripes on leaf petioles characterized the disease. Bacterial strains from bellflower induced symptoms the same as those on naturally infected plants and also induced the same symptoms found with lettuce bacterial varnish spot disease caused by Pseudomonas cichorii. On the basis of bacteriological characteristics, the bacterium was identified as Pseudomonas cichorii. This is the first report of bacterial brown spot disease of bellflower.
