摘　　要：热带牧草病害是影响其产量和品质的重要因素之一。本次在海南调查了10种禾本科和豆科牧草,共鉴定出了12种真菌性病害,其中国内新记录寄主病害9种,海南省新记录寄主病害3种。为害较重的有灰梨孢[Pyricularia grisea(Cke.)Sacc.]引起的双花草梨孢灰斑病、新月弯孢[Curvularia lunata(Wakker)Boedijn]引起的雀稗或鼠尾粟弯孢菌叶斑病、球黑孢霉[Nigrospora zimmerman(Sacc.)Mason]引起的热研11号黑籽雀稗叶枯病以及蝴蝶豆假尾孢(Pseudocercospora centrosematicola)引起的蝴蝶豆褐斑病。Diseases have a great influence on the yield and quality of tropical grass.In the paper,the diseases of ten species of tropical forage grass in gramineae and legume were investigated in Hainan.A total of 12 fungal diseases were identified,including 9 newly recorded host diseases in China and 3 newly recorded host diseases in Hainan.To a certain degree,Pyricularia gray spot caused by Pyricularia grisea （Cke.） Sacc.on Dichanthium annulatum,Curvularia leaf spot on Paspalum thunbergii and Sporobolus fertilis caused by Curvularia lunata （Wakker） Boedijn,and leaf blight caused by Nigrospora zimmerman （Sacc.） Mason on Paspalua atratum （Reyan No.11）,as well as brown spot caused by Pseudocercospora centrosematicola on Centrosema pubescens were more severe among these investigated diseases.
