为有效防控甘薯疮痂病，试用甲基托布津可湿性粉剂、多菌灵可湿性粉剂、苯菌灵可湿性粉剂、代森锰锌可湿性粉剂、硫酸链霉素可溶性粉剂、噻菌铜悬浮剂和硫磺?多菌灵悬浮剂7种药剂对甘薯疮痂病的防控效果进行对比试验。结果表明，50%硫磺?多菌灵悬浮剂500倍液、50%多菌灵可湿性粉剂400倍液和70%甲基托布津可湿性粉剂600倍液对甘薯疮痂病的防控效果较好。

In order to effectively control leaf scab disease of sweetpotato, experiments of six pesticides of Thiophanate-Methyl, Carbendazim, Benomy, Mancozeb, Streptomycin-Sulfate，Thiodiazole-Copper and Carbendazim-Sulfur were carried out to compare the leaf scab disease control efficacy on sweetpotato. The results showed that 50%Carbendazim-sulfur with 500 times, 50%Carbendazim-Sulfur with 500 times and 70%Thiophanate-Methyl with 600 times had better control effects on sweetpotato scab disease.
