摘　　要：为有效防控黄瓜细菌性角斑病等作物病害,研制了45%春雷霉素·喹啉铜悬浮剂,并确定了其最佳配方,通过田间药效试验评价该悬浮剂对黄瓜细菌性角斑病的防控效果.结果表明:45%春雷霉素·喹啉铜悬浮剂的最佳配方为春雷霉素4.5%,喹啉铜40.5%,润湿分散剂比例为MNS/901%,500LQ 2%,FD 3%,乙二醇5%,防腐剂卡松0.2%,消泡剂6300.5%,黄原胶0.2%,硅酸镁铝1%,柠檬酸3%,增效剂Prime 6%,去离子水补足.该配方悬浮性好、储存稳定性高,符合悬浮剂标准要求.田间试验显示,在黄瓜细菌性角斑病发病初期使用1000倍液喷雾,药后10 d防效达到96.77%,表明该制剂具有较好的防治效果.In order to effectively prevent and control crop diseases such as cucumber bacterial angular leaf spot,a formula of kasugamycin·oxine-copper 45% was developed,and its optimal formula was determined.The control effect of kasugamycin·oxine-copper 45% on cucumber bacterial angular leaf spot was evaluated through field efficacy trials.The optimal formula of kasugamycin·oxine-copper 45%SC was as follows:4.5% kasugamycin,40.5% oxine-copper,1%MNS/90,2%500LQ,3%FD,5% ethylene glycol,0.2% Kathon preservative,0.5% defoamer 630,0.2% xanthan gum,1% magnesium aluminum silicate,3% citric acid,6% synergist Prime,with DI water topping up to 100% in total.This formulation has excellent suspension property,good storage stability,and all technical indicators meet the standard requirements of the suspension agent.The field experiment showed that spraying 1,000 times solution of this formulation at the initial stage of cucumber bacterial angular leaf spot,the control effect could reach 96.77% 10 days after application,indicating that the preparation has a good control effect on cucumber bacterial angular leaf spot.
