摘要
为有效控制马铃薯早疫病危害,筛选出适合拉萨地区防治马铃薯早疫病的高效药剂。以“藏农薯1号”为试验品种,选用4种新型高效低毒药剂,在拉萨马铃薯试验基地开展田间药效防治试验。结果表明:药剂325 g/L苯甲·嘧菌酯悬浮剂和井冈霉素·枯草芽孢杆菌可湿性粉剂处理的防治效果和产量表现较好,防效分别为86.81%和76.84%,每667 m^(2)产量分别为3 059.20 kg和3 303.65 kg。两种药剂均可作为防治马铃薯早疫病的首选药剂,可在大田交替使用。
In order to efectively control harm of potato early blight,eficient pesticides suitable for preventing and controlling potato early blight in Lhasa area were screened.A field efficacy control experiment was conducted at the Lhasa potato experimental base,using"Zangnongshu No.1"as the experimental variety and four new high-efficiency and low toxicity Pesticides.The results showed that the treat-ments with the pesticide 325g/L benzy|azoxystrobin suspension and Jinggangmycin Baillus subtilis wettable powder showed better control efect and yield performance,with control efcts of 86.81%and 76.84%,and yields of 3059.20 kg and 3303.65 kg per mu,respectively.Therefore,both of the above pesticides can be used as the preferred agents for preventing and contolling potato early blight,and can be used alternately in the field.
