In 2005, Circular to elliptical brown necrotic leaf spots, were observed on young leaves of Banana(Musa acuminata L.) plantion under plastic cover in Mazandaran&Gorgan provinces. The rhizomes and pseudostems were not affected. A gram-negativebacterium with yellow mucoid colonies was isolated from the leaves on sucrose and glucose nutrient agar. All isolates were negative in oxidas, and positive in catalase reaction. Non of isolates did not produce green or blue pigment on KB medium. On the basia of phenotypic charachteristics pathogenicity test was confirmed with inocoulation of bacterial suspension to Banana plants. The causal agent of bacterial necrotic and leaf spot of banana was recognized asXanthomonascampestris. This is the first report ofbacterial necrotic and leaf spot of banana in Iran.
