摘  要：
[目的]明确纳他霉素与6种杀菌剂对木霉毒力的差异并比较纳他霉素与6种杀菌剂混配对木霉M23的毒力。[方法]采用菌丝生长速率法测定纳他霉素和6种不同杀菌剂以及纳他霉素与6种杀菌剂混配对木霉M23的室内毒力。[结果]6种不同杀菌剂对木霉的毒力不同,其EC_(50)分别为0.448 4、0.709 9、1.390 8、8.648 3、12.448 1和18.185 6 mg/L;与6种杀菌剂相比,纳他霉素表现出较好的杀菌效果,其EC_(50)为1.551 1 mg/L,与百菌清相近。混配试验结果表明,纳他霉素与百菌清以3∶1比例、与多菌灵以1∶6比例、与苯醚甲环唑以1∶6比例混配均具有最高的共毒系数,其值分别为250.020 0、373.990 3和189.194 4。[结论]纳他霉素与百菌清(3∶1比例)、多菌灵(1∶6比例)、苯醚甲环唑(1∶6比例)混配均具有较好的增效作用,可进一步用于生产实践。

摘  要：
[Objective] The aim was to determine the toxicity difference of natamycin and six fungicides against Trichoderma viride,and compare toxicity of mixture of natamycin and six fungicides against Trichoderma viride M23.[Method] By the method of mycelium growing,the indoor toxicity of natamycin and six fungicides against Trichoderma viride M23 was determined.[Result] The results showed that the 6 fungicides had different control efficiency,with their EC_(50) values of 0.448 4,0.709 9,1.390 8,8.648 3,12.448 1 and 18.185 6 mg / L;compared with the 6 fungicides,natamycin show good control effect with its value of 1.551 1 mg / L,similar to chlorothalonil.The mixprocess experiment showed obvious synergies,that the mixture of natamycin and chlorothalonil with ratio of 3∶ 1 had the highest cotoxicity coefficient of250.020 0;natamycin and carbendazim with ratio of 1 ∶ 6 had the highest cotoxicity coefficient of 373.990 3;natamycin and difenoconazole with ratio of 1∶ 6 had the highest cotoxicity coefficient of 189.194 4.[Conclusion] The experimental results show that the three mixed proportions of the fungicides( natamycin:chlorothalonil = 3∶ 1,natamycin:carbendazim = 1∶ 6,natamycin:difenoconazole = 1∶ 6) have good synergistic effect and could be used in further production.
