| 摘 要： | 竹叶枯型丛枝病为害新梢嫩叶,造成叶枯、梢枯,连年发病引发小枝丛生,该病发展快,发病时间短,季节性强。老病枝连年发病,使新梢发病率常达90％以上。病叶上普遍产生黑褐色点状的子囊菌子实体。用子囊孢子对健壮株枝梢作人工接种,第2年新梢嫩叶发病,具典型症状。经鉴定该病病原菌为竹暗球腔菌(Phaeosphaeria bambusae Miyake et Hara)。刚竹属中的淡竹(Phyllostachys glauca)、桂竹(Ph. bambusoide)和融安刚竹(Ph. sp.)发病最重。3月间竹腔注射20％粉锈宁乳油剂(1∶200)1次,即可明显减轻该病的发生。

The diseased branches come on in successive years. The new tip incidence of a disease are more than 90%. The branch and tops were inoculated artificialy, their new tips and tender leaves were diseased with typical symptom next year. Phaeosphaeria bambusae Miyaue et Hara was the disease-producing germ. Phyllostachys glauca, Ph. bambdsoide and Ph. sp. were diseased most seriousely. Bamboo cavity were injected with Bugleton emut-sion (1:200) once on March, the diseases have eased obviously. |
