Abstract

In July 1998, a sudden wilt of 'Star Ruby' grapefruit (Citrus paradisi Macf.) occurred in Israel in a region with a warm Mediterranean climate. The wilt of the middle and upper canopy of main limbs was accompanied by gum oozing from the affected branches. The bark of these branches attained a dark colour and the epidermis sloughed off easily revealing a mass of black powder, resulting from copious sporulation of dark conidia. Both the bark and the xylem were intensively colonized with mycelium. The fungus was identified as Scytalidium lignicola Pesante, based on the characteristic mixture of some colourless and dark conidia, produced in branched chains by conversionof the vegetative hyphae. Artificial inoculations induced typical disease symptoms and the fungus was reisolated, thus confirming Koch's postulates. Similar symptoms appeared in 'Star Ruby' interim segments which had been cut and top grafted with various citrus cultivars. This is the first detailedreport of pathogenicity of S. lignicola to citrus trees. It is postulated that the disease developed after predisposition of 'Star Ruby' grapefruit trees by comprehensive pruning followed by extremely hot conditions.
