[目的]制备35%氟环唑·嘧菌酯悬浮剂,评价悬浮剂的生物活性。[方法]采用湿法砂磨工艺制备35%氟环唑·嘧菌酯悬浮剂,对配方中润湿分散剂、增稠剂、防冻剂、消泡剂和防腐剂等助剂进行筛选,对该悬浮剂的悬浮率、分散性、热贮稳定性等性能指标进行测试。采用菌丝生长速率法测定悬浮剂对水稻纹枯病病菌的毒力,评价悬浮剂的生物活性。[结果]35%氟环唑·嘧菌酯悬浮剂的最佳配方为氟环唑15%,嘧菌酯20%,Emulson AG TRST 4%,TERSPERSE 2500 2%,硅酸镁铝0.5%,黄原胶0.15%,乙二醇5%,防腐剂S30 0.5%,消泡剂AF1501 0.5%,水补足至100%。35%氟环唑·嘧菌酯悬浮剂对水稻纹枯病病菌的生物活性高于12.5%氟环唑悬浮剂...

[Aims] The optimum formula of epoxiconazole · azoxystrobin 35% SC was obtained, and the bioactivity was tested. [Methods] The formulation was identified through screening main adjuvants such as wetting-dispersing agent, thicking agent, anti-freeze agent, defoaming agent, preservative agent and etc.. The epoxiconazole ·azoxystrobin 35% SC was prepared by wet grinding technology. The tests were conducted on the parameters including suspension rate, dispersion and storage stability. The toxicity of epoxiconazole · azoxystrobin 35% SC on Rhizoct...
