摘　　要：[目的]为了充分发挥杀菌剂的药效,改善其对猕猴桃溃疡病的田间防治效果开展本研究。[方法]采用多种施药方式相结合的方法进行杀菌剂防治猕猴桃溃疡病田间小区试验。[结果]在600 g a.i./hm^(2)剂量下,采用喷雾、病斑涂抹和灌根相结合的施药方式,试验药剂20%FM-86悬浮剂对猕猴桃叶片和枝条溃疡病的防效分别为90.68%和86.86%,防效较为理想。随着剂量降低和施药方式的简化,试验药剂对猕猴桃溃疡病的防效呈现降低趋势。[结论]不同施药方式对药剂防治猕猴桃溃疡病的效果有明显影响,可通过施药方式的改善来提高药剂防效。[Aims]This study was conducted to give full play to the efficacy of fungicides and improve their field control effect on kiwifruit canker disease.[Methods]Field plot trials were conducted using different application methods to test the efficacy of bactericide against kiwifruit canker disease.[Results]At the dosage of 600 g a.i./ha,using the combined methods of spray,spot painting and root irrigation,FM-8620%suspension concentrate showed an ideal control effect against kiwifruit canker disease on leaves and branches of 90.68%and 86.86%,respectively.With the reduction of dosage and simplification of application methods,the control efficacy of tested bactericide against kiwifruit canker disease showed a decreasing trend.[Conclusions]Different application methods have significant impacts on the control efficacy of bactericide in controlling kiwifruit canker disease,so the efficacy of bactericide can be increased by improving the application methods.
