| 摘 要： | 为明确氰烯菌酯与己唑醇不同比例混配对小麦纹枯病菌联合作用类型，采用菌丝生长速率法测定了氰烯菌酯与己唑醇及其5种配比对小麦纹枯病菌的毒力。结果表明，氰烯菌酯与己唑醇及其1:5、1:7、1:9、1:11、1:13等混配组合对禾谷丝核菌的EC50分别是0.212、0.339、0.227、0.207、0.213、0.315、0.320 mg/L，5种混配组合对禾谷丝核菌的增效系数(SR)分别是1.35、1.52、1.51、1.02、1.02；对立枯丝核菌的EC50分别是0.452、2.984、1.091、1.139、1.217、1.280、1.781 mg/L，增效系数(SR)分别是1.41、1.54、1.57、1.59、1.20；氰烯菌酯与己唑醇1:(7~9)混配对小麦纹枯病菌有增效作用。

| Abstract: | In order to clarify the synergistic effects of mixed JS399-19 and Hexaconazole to Rhizoctonia cerealis and R. solani and to find the best mixed ratio of two preparations, the JS399-19 and Hexaconazole and their mixtures-made up by mixing the two pesticides in five different ratios, on Rhizoctonia cerealis and R. solani were tested by mycelial growth rate method. Experimental results demonstrated that EC50 of JS399-19, Hexaconazole, and their five different ratios to Rhizoctonia cerealis were 0.212, 0.339, 0.227, 0.207, 0.213, 0.315, 0.320 mg/L. The efficiency coefficients of the five different ratios to Rhizoctonia cerealis were 1.35, 1.52, 1.51, 1.02, 1.02. Experimental results demonstrated that EC50 of JS399-19, Hexaconazole, and their five different ratios to R. solani were 0.452, 2.984, 1.091, 1.139, 1.217, 1.280, 1.781 mg/L. The efficiency coefficients of the five different ratios to R. solani were 1.41, 1.54, 1.57, 1.59, 1.20. The mixed ratio of two preparation 1:(7-9) to Rhizoctonia cerealis and R. solani have synergistic effects. |
