Author(s):  
E. Punithalingam

Abstract A description is provided for Septoria vignae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Vigna unguiculata (cowpea) (= V. sinensis); also on V. lanceolata. DISEASE: Leaf spots of cowpea. The visible symptoms are chocolate brown to rust brown spots, paler below with pale or whitish centres. The spots are amphigenous but more prominent on the upper side of the leaf, usually rounded or irregular, up to 6 mm wide, occasionally coalescing to form larger spots with well defined margins. GEOGRAPHICAL DISTRIBUTION: Africa (Botswana, Kenya, Nigeria, Tanzania, Uganda, Zaire, Zambia, Zimbabwe); Asia (India, Hong Kong); Australasia and Oceania (Australia, Queensland, New South Wales); South America (Brazil, Bahia). TRANSMISSION: No specific studies reported; presumably by conidia dispersed by water splash. The fungus might overwinter on crop debris left in the field.
