1973年在也门的瓦迪利里地区首次报告了香蕉果斑(FAO,1975).在该国已蔓延到几个其他产蕉区并成为香蕉生产的一个重要问题.不正常的典型症状已由Waller和Hin-dorf描述过(1977).斑点在花梗、幼果和花序苞片上产生.被害植株组织表面首先出现污斑、退绿和小圆斑.这些斑点逐渐扩大、变黑并发展成油状水清斑.随着果实的发育,果皮裂开,这样,引起果腐的腐生生物就容易侵入并引起整个果串萎缩.
Banana fruit spots were first reported in the Wadi Rally region of Yemen in 1973 (FAO, 1975), where it has spread to several other banana producing areas and has become an important issue for banana production. Typical abnormal symptoms have been Waller and Hin-dorf (1977). Spots are produced on pedicels, young fruits and inflorescence bracts. The diseased plants first appear greyish, faded green and small round spots on the tissue surface, which gradually enlarge, darken and develop into oily Water clear spot.With the development of fruit, the peel split, so that the saprophytic organisms that cause fruit rot easily invade and cause the whole fruit atrophy.
