摘　　要：为筛选出防治猕猴桃褐斑病的高效药剂,特对6种杀菌剂的田间防治效果进行了综合评价。结果表明,40%苯甲·咪鲜胺水乳剂对猕猴桃褐斑病的防治效果最好,每隔7 d施1次,连施3次后的相对防治效果为81.05%,其病情指数仅为13.24,极显著优于其他药剂。同时,其可溶性固形物含量为13.8%,比对照高19.0%;其产量也最高,为855.7 kg·(667 m^(2))^(-1),比对照高21.4%。栽培上可将此杀菌剂作为防治猕猴桃褐斑病的理想药剂。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.
