摘　　要：落叶松癌肿病是危害兴安落叶松的重要枝干病害,该病在内蒙古大兴安岭林区全境内都有不同程度的发生,近年来在一些林业局的人工幼龄林发生严重,尤其以20年左右的落叶松人工幼龄林发病严重。国内对此病的研究较少,从克一河林业局的实际生产需要出发,进行了室内外药效测定和林间防治试验,发现以营林措施(卫生伐+修枝)结合病部人工涂抹70%精品甲基托布津与机油混合液的综合防治技术为最佳。Larch canker was a disease which affects the main trunk of Dahurian Larch,making the outer layer come away to expose the inside of the stem.The disease spread Daxing Anling Inner Mongolia in varying degrees.Recently some manmade sapling forests have been in a serious situation especially twenty years old sapling trees.The researches about it in our country are relatively less,From the practical aspect,After testing the efficiency of medicine indoors and outdoors and preventive treatment in the forest,the best way was the blend of construction of forestry(sanitation cutting and pruning)and miscible liquids daubed by workers,which was made of seventy percent thiophanate methyl and engine oil.
