桑树是蚕桑产业的重要物质基础。为确保桑树健康成长,促进产业发展,桑树病害的有效识别与及时防控尤为重要。真核微生物、原核微生物及非细胞类病毒中均存在能引发桑树传染性病害的病原微生物。其中由真核微生物引起的桑里白粉病与桑椹菌核病,原核微生物引起的桑青枯病与桑疫病是爆发频繁、危害极大的桑树病害。本文就这四种桑树病害的病原、侵染循环、病害识别及防治方法等进行系统梳理,并简要介绍几种非细胞类微生物引起的桑树病害,以期为生产上防治相关病害提供参考。

Identification and control of several diseases commonly occurred in mulberries

Mulberry is a crucial material basis for healthy development of sericulture .It is vital for the effective identification and prompt control of the diseases occurred in mulberries to ensure both the healthy grow th of mulberry and the development of mulberry‐based industry . Pathogens capable of infecting mulberries are widely discovered in eukaryotic microorgan‐isms ,prokaryotic microorganisms and viruses ,among w hich ,four kinds of pathogens are the most harmful ,including the mulberry pow dery mildew and sclerote disease of mulberry fruit caused by pathogens of eukaryotic microorganisms ,and mulberry bacterial wilt and mulberry bacterial blight caused by pathogens of prokaryotic microorganisms .In this study , the pathogens of four kinds of mulberry diseases and the infection cycles ,disease identifica‐tion and disease control methods ,as well as several virus diseases were summarized ,which would be helpful for the effective control of these diseases .
