摘要
在河南郑州市发现金叶女贞新病害——叶斑病.病原菌经分离和柯赫氏法则验证,为一种棒孢属真菌.通过形态学观察及与相似种的比较,确定其分类地位为蔓荆子棒孢一新的专化型,即蔓荆子棒孢女贞专化型(Corynespora viticis Guo f.sp.ligustri Zhang).该病害在7～10月发生,叶片上会出现大量近圆形、带轮纹的褐色病斑,严重时会导致叶片大量脱落.
A new disease of Ligustrum vicaryi in Zhengzhou, Henan Province has been found. Its pathogen has been isolated, proved by the rule of Koch and identified as Corynespora viticis Guo f. sp. ligustri Zhang by morphologic observation and comparison with similar species. From July to October there are plenty of leaf-spots on Ligustrum vicaryi, which are round, brown, and with rings. When the disease becomes serious many leaves shed off the branches.
