摘　　要：荞麦是云南山区的主要粮食作物之一,荞麦白霉病严重危害荞麦的生产,研究从昭通采回的病样,经单孢分离,显微观察病原,明确其致病病原为无性态真菌的异形柱隔孢(Ramularia anomala Peck),确定为荞麦白霉病,同时进行了生物学特性和生长条件实验研究,结果表明该菌是一类对营养需求不高,对环境适应力强的病原菌。该病为昭通市首次报道。本研究为生产上防治荞麦白霉病提供了依据。The buckwheat,which is one of major crops at mountain,often causes damage seriously by frosty mildew constantly.The disease of frosty mildew distributed widely in Yunnan.The pathogen was isolated and identified as Ramularia anomala Peck by morphological characteristics comparison.The biological characteristics of the pathogen were studied.The results showed that the pathogen had strong adaptability in the environment with on its biological character.These results can guide buckwheat frosty mildew control.
