云南桑树褐斑病的发生与防控

Occurrence and Control of Mulberry Brown Spot Disease in Yunnan

蚕桑产业是云南农业产业化主导产业之一,发展势头强劲、市场潜力大,云南现成为全国栽桑养蚕第三大省份。然而,桑树病害的发生成为影响蚕桑产业稳定发展的重要因素,其中以桑褐斑病最为严重。桑褐斑病是云南桑树最重要的叶部病害,由桑褐斑壳丰孢[Phloeospora maculans (Bereng.) Allesch]感染引起,发病率高,危害严重,严重影响蚕桑生产发展。国内外学者对桑褐斑病的研究主要集中于桑褐斑病的分布、危害、病原、症状、传播途径、发病条件及防治方法等方面。本文从以上几个方面进行综述,以期为桑褐斑病更深入的研究及防治提供参考。
