摘要
采用湿法研磨工艺研制12%氟唑菌酰胺·苯醚甲环唑悬浮剂,确定其最佳配方,并通过田间药效试验评价该悬浮剂对小麦白粉病的防治效果。12%氟唑菌酰胺·苯醚甲环唑悬浮剂的最佳配方为氟唑菌酰胺7%、苯醚甲环唑5%、润湿剂W-6001%、分散剂NS-500LQ 2%、分散剂DS-8093%、防冻剂乙二醇5%、防腐剂卡松0.2%、有机硅消泡剂15110.5%、增稠剂黄原胶0.2%、增稠剂硅酸镁铝1%、pH调节剂柠檬酸0.2%、增效剂Prime 6%,去离子水补足100%。所制制剂悬浮率在99%以上,储存稳定性合格。在小麦白粉病发病初期采用12%氟唑菌酰胺·苯醚甲环唑悬浮剂1000倍液喷雾,药后10 d的防效达到97.4%。该制剂对小麦白粉病具有较好的防治效果。
Fluxapyroxad·difenoconazole 12%SC was developed using the wet grinding process,and its optimal formula was determined.The control effects against wheat powdery mildew were evaluated by field trials.The optimal formula of fluxapyroxad·difenoconazole 12%SC was as follows:fluxapyroxad 7%,difenoconazole 5%,wetting agent W-6001%,dispersant NS-500LQ 2%,dispersant DS-8093%,antifreeze ethylene glycol 5%,preservative Kathon 0.2%,silicone defoamer 15110.5%,thickener xanthan gum 0.2%,thickener magnesium aluminum silicate 1%,pH regulator citric acid 0.2%,synergist Prime 6%,and deionized water adding to 100%.The suspension rate of the formula reached 99%,and the storage stability met the standard requirements.At the initial stage of wheat powdery mildew,fluxapyroxad·difenoconazole 12%SC was sprayed with 1000-fold dilution,the control effect reached 97.4%at the 10th day after spraying.The formula had good control effect on wheat powdery mildew.
