[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-86 20％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.
