摘　　要：采用人工接种病原菌,诱导金叶女贞感病,同时选用10种农药研究防治效果。结果表明:百菌清、日本甲基托布津预防效果最好,未发病;爆菌的预防效果较好,发病率为34.21%～35.39%,病斑大小为0.25～0.34cm;美国多菌灵、成标、代森锰锌、杀毒矾的预防效果较差,发病率58.23%～86.34%,病斑大小为0.32～0.86cm;可杀得、甲霜灵锰锌、国产多菌灵3种农药的预防效果很差,发病率100%,病斑大小为0.36～1.35cm。百菌清、美国多菌灵、日本甲基托布津、爆菌、代森锰锌、甲霜灵锰锌、国产多菌灵的治疗效果很好,未发病;可杀得、成标、杀毒矾的治疗效果次之,4d的发病率为32.37%～36.34%。Ten fungicides were used to control brown spot disease of Ligustrum vicaryi. The results showed that the best preventive fungicides were ehlorothalonil and Japanese thiophanate-methyl with the disease infection rate of zero;peracetic acid had better preventtive effect which infection disease rate and diameter of disease spot were 34. 21%--35.39%, 0. 25--0. 34 cm respectively; American carbendazim, kumulus, mancozeb and sandofan had lower preventtive effect which were 58. 23 %--86. 34%, 0. 32-0. 86 cm respectively; kocide, metalaxyl-MZ and Chinese carbendazim has no preventive effect on this disease which diameter of disease spot were 0. 36--1.35 cm. The best treatment fungicides were chlorothalonil, American carbendazim, Japanese thiophanate-methyl, peracetic acid, maneozeb, metalaxyl-MZ and Chinese carbendazim without disease spot; the lower were kocide, kumulus, sandofan the infection disease rate of 4 d were 32. 37%--36. 34%.
