摘　　要：采用生长速率法进行多菌灵、甲基托布津、扑海因、三唑酮、代森锰锌、福美双6种药剂对轮纹病菌的毒力测定。结果表明:多菌灵、甲基托布津和扑海因对轮纹病菌具有较好的抑制作用;采用生长速率法和孢子萌发抑制试验,进行多菌灵∶扑海因=1∶1、多菌灵∶扑海因=2∶1、甲基托布津∶扑海因=1∶1、甲基托布津∶扑海因=2∶1这4种混配药剂对轮纹病菌毒力测定,结果表明:除了多菌灵∶扑海因=2∶1的处理外,其余3个处理共毒系数均大于100,说明混配后具有明显的加性效应,其配比可作为药剂加工的混配比例。The toxicity of 6 kinds of organic fungicides, Carbendazim, Thiophanatemethy WP, Inprodione, Triadimefon, Mancozeb and Thiram was measured against Macrophoma Kawatsukaii by mycelium growth rate test, Results showed that Carbendazim, Thiophanatemethy WP and Inprodione had better inhibitive effect on Macrophorna Kawatsukaii. The effect of mixed medicament of Carbendazim ： Inprodione = 1 ： 1, Carbendazim ： Inprodione = 2 ： 1, Thiophanatemethy WP ： Inprodione= 1 ： 1, Thiophanatemethy WP ： Inprodione= 2 ： 1 were tested. It indicated that except Carbendazim ： Inprodione：2 ： 1 ,the other 3 treatments all had obvious additative effect.
