(On leaves and fruits, rarely on young twigs and buds, leaf spots scab-like, amphigenous, diffuse, subcircular, olivaceous to dark brown or almost black, surrounded by a paler brown halo.

生息環境

基質
On Eriobotrya japonica, Europe, Great Britain, Surrey, Wisley, 23 Dec. 1966, A.V. Brook (IMI 123946), on Pyrus spp. collections from B, G, HBG, IMI, J, LE, M. [3]
気候
Worldwide in temperate and subtropical regions wherever pears are grown (see CMI Map 367, ed. 2, 1968) [2]

病害

Causes scab or black spot of pear, which results in loss of quantity and quality of fruit. The disease attacks shoots, buds, leaves and fruit, symptoms and etiology being very similar to those of apple scab caused by V. inaequalis on Malus spp. (CMI Descript. 401). Dark, more or less circular scabs are produced on leaves and fruit, often with some growth distortion. Infection of young wood is more common than with apple scab and causes pale brown blister-like lesions which burst to release conidia in the following year. [2]
