通过对35%毒氟磷·啶氧菌酯悬浮剂助剂的筛选实验,确定了最佳制剂配方:毒氟磷20%,啶氧菌酯15%,Teva-1118 3%,Antarox B/848 1%,AEO-3 1%,硅酸镁铝1%,黄原胶0.2%,凯松0.3%,防冻剂乙二醇4%,有机硅消泡剂0.2%,用去离子水补至100%。根据上述配方加工成的35%毒氟磷·啶氧菌酯悬浮剂,悬浮率在90%以上,其他指标合格。大田药效试验表明,35%毒氟磷·啶氧菌酯悬浮剂对西瓜病毒病有很好的防治效果,在120 g/hm2用量下叶面喷雾,对西瓜病毒病的防效达到99.4%。
Through the screening experiments of 35% of the drug agent, the best preparation formula was determined: 20% of toxic fluorine phosphorus, 15% of picoxystrobin, 3% of Teva-1118, 3% of Antarox B / 848 1% of AEO-3, 1% of magnesium aluminum silicate, 0.2% of xanthan gum, 0.3% of kaixin, 4% of antifreeze ethylene glycol and 0.2% of silicone defoamer, %. According to the above-mentioned formula into 35% of the poisoning of fluticasone picoxystrobin suspension, the suspension rate of 90% or more, other indicators of qualified. Field efficacy trials showed that 35% of the drug floxadin aerosol suspension of watermelon virus disease has a good control effect, the amount of 120 g / hm2 foliar spray, the control effect of watermelon virus disease reached 99.4% .
