Cercospora fuligena. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Cercospora fuligena. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Lycopersicon esculentum. DISEASE: Leaf spot or leaf mould of tomato; the latter common name is best retained for the more important pathogen (Fulvia fulva (Cooke) Cif.) on the same host. Early symptoms are faint, sunken, chlorotic areas with indefinite margins; the infected areas become necrotic and have an indefinite discoloured halo on both leaf surfaces; defoliation can occur (35, 52; 53, 4592). GEOGRAPHICAL DISTRIBUTION: Africa (Ivory Coast, Nigeria); Asia (Cambodia, China, India, Japan, Malaysia, Philippines, Thailand, Vietnam); Australasia & Oceania (New Caledonia, New Hebrides, Papua New Guinea, Solomon Islands) (CMI Map 382, ed. 2, 1970). Unmapped new records are: Burundi (50, 2635), Hong Kong, Togo (Herb. IMI) and USA (Florida. ; 53, 4592). A record from Mexico (Zevada, Yerkes & Niederhauser; 36, 2) is considered doubtful. TRANSMISSION: No studies reported.
