摘　　要： 阴香的用途广泛,具有重要的经济价值。阴香叶斑病的危害使感染树叶片树体的叶色变黄、树势衰弱,严重影响了其使用价值与经济价值。本文报道多菌灵Carbendazim、代森锌锰(Dithane M45代森锰锌)、露易、腈福、高登、菌可得、炭疽福美(thiram+ziram)、菌速克可湿性粉剂及叶青双等10种杀菌剂对阴香叶斑病病原菌抑制作用的研究结果,研究表明,25%火把可湿性粉剂对阴香叶斑病病原菌菌落生长的速率、孢子的萌发率及叶片感染率的抑制作用最大,其次为露易和腈福2种杀菌剂,其余7种对阴香叶斑病病原菌的抑制作用较差。 The cinnamoumum burmannü, being used for making many kinds of products, has the important economic value. For the infected trees are feeble and their leaves are yellowish, the leaf spot greatly decreases the economic and practical values of cinnamoumum burmannü trees. This article reported the research results on the commonly used fungicides, such as prochloraz manganese, luyi, carbendazim＋thiram, carbendazim, mancozeb, thiram＋myclobutanil, carbendazim＋thiram, thiram＋ziram, bismerthiazol and so on, inhibition to the pathogen causing the leaf spot of cinnamoumum burmannǜ. The results indicated that 25% prochloraz manganese wet powder had the best effects on the inhibition of the pathogen colonial growth, spore germinating and infecting to the cinnamoumum burmannü tree leaves, next for luyi and thiram＋myclobutanil, but the other seven had not significant effects on these.
