金叶女贞在6~7月和9~10月叶片上会出现许多不规则形状的病斑,俗称叶斑病,严重时会导致受害叶片早落。经研究其病原为假尾孢真菌Pseudocercosporasp.。通过人工接菌,观察了病害的症状、发病规律、培养特性、形态特征,以及温度、pH对菌丝体生长的影响。经室内杀菌剂筛选试验,用10g/L百菌清杀菌效果较好。 Golden leaf privet in June to July and September to October leaves will appear many irregular shape of the lesion, commonly known as leaf spot disease, serious injury will lead to early leaves fall. Its pathogen is Pseudocercospora sp. By artificial inoculation, the symptoms, pathogenesis, culture characteristics, morphological characteristics of the disease and the effects of temperature and pH on mycelial growth were observed. The indoor fungicide screening test, with 10g / L chlorothalonil bactericidal effect is better.
