摘　　要：柳树两种叶斑病在抚顺地区发生普遍,为害严重,使树木在生长季节大量落叶,影响正常生长。经大量病组织切片分离培养接种试验证明致病菌为Phyllostiota salicicola Thum及Hyaloceras sp,并对上述两种病原菌的形态及防治进行初步探讨。经试验50％多菌灵和70％甲基托布津500—1000倍液防治效果达80％以上。Two willow leaf diseases caused by the pathogenic Fungi Phyllasticta saliciwla Thum and Hyaloceras sp. were studied to learn their morphology and prevention and control. Through plenty of experiments, it was found that using 50 percent earbendazal (1:500—1000)or 70 percent Thiophanate methy 1 (1:500—1000) to prevent the diseases is distinctly effective. The prevent rate amounts to 80 percent.
