Abstract A description is provided for Ascochyta heveae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Hevea brasiliensis. DISEASE: Marginal leaf scorch or rim blight of rubber leaves (Hevea brasiliensis). Early symptoms on mature leaves are groups of minute, yellowish spots merging with one another as they develop forming dry brown or greyish patches with a paler centre and a purplish brown border. Dry spots extend from the leaf margin inwards towards the midrib between the veins finally coalescing with one another so that the leaf is edged with a discoloured zone all the way round (Petch, 1921). GEOGRAPHICAL DISTRIBUTION: Africa (Zaire); Asia (Malaysia, Malaya, Sarawak, Sri Lanka). TRANSMISSION: No studies reported; conidia presumably dispersed by water splash.
