摘　　要：为探究不同杀菌剂对苹果锈病防治效果及安全性,以甘肃省白银地区的患叶锈病苹果树为研究对象,分别考察了发病前开展预防试验和病菌侵染后开展治疗试验时,不同处理药剂对苹果树叶锈病的防治效果,对比了不同药剂施用后苹果果实横径、纵径以及单果质量的差异。结果显示:在发病前施用不同处理药剂,烯唑醇乳油防治效果显著高于其他药剂,病菌侵染后施用不同处理药剂试验中,第1次用药后及第3次用后药防治效果最好的药剂均为三唑酮乳油,防治效果显著高于其他药剂;三唑酮乳油处理下的果实相较于对照果实品质受影响相对严重,吡唑醚菌酯悬浮剂处理下果实品质受影响最小。In order to explore the control effect and safety of different fungicides on apple rust disease,apple trees affected by leaf rust disease in Baiyin area of Gansu Province were taken as the research objects,and the control effect of different treatment agents on apple leaf rust disease was investigated respectively during the prevention test before the outbreak and the treatment test after the infection of bacteria.The differences of transverse diameter,longitudinal diameter and single fruit quality of apple fruit after different application of different insecticides were compared.The results showed that in the test of different treatment agents applied before the onset of disease,the control effect of enazolol cream was significantly higher than that of other agents.In the test of different treatment agents applied after the infection of bacteria,the best control effect of triazolone cream was significantly higher than that of other agents.Compared with the control group,the effect of triazolone cream on fruit quality was relatively serious,and the effect of pyrazolacetin suspension on fruit quality was minimal.
