Abstract:
In order to screen out high-efficiency fungicides for the control of kiwifruit brown spot,the field control effects of six fungicides were comprehensively evaluated.The results showed that the treatment of40% benzophenone prochloraz water emulsion had best control effects on kiwifruit brown spot disease.The relative control effect was 81.05% after three consecutive applications,and its disease index was only 13.24,which was significantly best than other agents.At the same time,the soluble solid content was 13.8%,which was 19.0% higher than the control;The equivalent yield was also the highest,which was 855.7kg·(667m~2)
-1 respectively,24.4% higher than the control.In conclusion 40% benzophenone prochloraz water emulsion can be used as an ideal fungicide to control kiwifruit brown spot in cultivation.
