摘　　要：在陇东生态条件下,以苹果园主要杀菌剂桶混配方“苯醚甲环唑+代森锰锌”为指示杀菌剂,田间测定桶混添加“天达-2116+迈丝”和“阿泰灵+迈丝”对防治苹果黑星病和苹果斑点落叶病药剂的减量效应。结果表明:在确保对苹果生长发育安全,对2种病害均有理想防治效果的条件下,桶混添加“天达-2116+迈丝”和“阿泰灵+迈丝”均可将参试杀菌剂桶混配方中10%苯醚甲环唑WG和80%代森锰锌WP的施用量分别降至稀释3500倍和1000倍,较常规制剂用量分别减少用药28.57%和40%;第6次药后10 d、30 d和52 d,对苹果黑星病的防治效果分别达到88%、85%和81%以上,以桶混添加“阿泰灵+迈丝”的较高;对苹果斑点落叶病的防治效果分别达到78%、74%和64%以上,以桶混添加“天达-2116+迈丝”的较高。可见,桶混添加“天达-2116+迈丝”和“阿泰灵+迈丝”可明显减少苹果园杀菌剂的施用量,建议在生产上推广应用。With fungicides barrel mixing of Difenoconazole and Mancozeb as the indicator in apple orchards,the reducing effects of barrel mixing Tianda-2116,Atailing and Maisi on apple scab and alternaria blotch disease were measured in the field under the ecological conditions of East Gansu.The results showed that under conditions of safe apple growth and development,and effective control of two kinds of diseases,the addtion of Tianda-2116+Maisi,Atailing+Maisi to mixing barrel could dilute 10%Difenoconazole WG and 80%Mancozeb WP 3500 and 1000 times,respectively.Compared with conventional dosages,the amounts were reduced by 28.57%and 40%,respectively.After 10 d,30 d and 52 d of the sixth time application,the control effect on apple scab disease was over 88%,85%and 81%,respectively,among which barrel mixing Atailing and Maisi were better.At the same time,the control effects on apple alternaria blotch disease were over 78%,74%and 64%,respectively,among which barrel mixing Tianda-2116 and Maisi were better.In conclusion,both barrel mixing Tianda-2116+Maisi,and Atailing+Maisi can decreased fungicides amounts obviously,it is suggested applying in production.
