多花黑麦草斑驳病毒病：病株出现萎缩，并在叶片上出现黄色条斑。机械接种可引起多花黑麦草、小麦、大麦、燕麦、黑麦等多种禾本科牧草较高频率的感染；大麦、谷子、鸭茅等还伴有坏死症状。在日本草地中多花黑麦草发病比较严重。传播途径：汁液传染。自然寄主：日本的自然寄主是多花黑麦草Loliummultiflorum和鸭茅Dactylisglomerata。人工接种可侵染的植物：燕麦Avenasativa、鸭茅Dactylisglomerata、紫羊茅Festucarubra、大麦Hordeumvulgare、黑麦Secalecerale、谷子Setariaitalica、小麦Triticumaestivum。病害的防治：可用抗病品种控制病害。
