【摘要】 设置红乳葡萄避雨栽培区和露地栽培区,以戊唑醇等6种杀菌剂为试材,以清水为对照,研究6种杀菌剂在避雨和露地栽培条件下对红乳葡萄黑痘病的防治效果。结果表明,避雨栽培条件下6种杀菌剂对红乳葡萄叶片和果实的黑痘病均有较好的防治效果,其中叶片防效达90.4%以上,果实防效达97.8%以上。露地栽培条件下,6种杀菌剂之间防效差异显著,80%波尔多液、25%戊唑醇、40%氟硅唑对葡萄黑痘病的防治效果显著高于40%高纯多菌灵、75%百菌清和80%代森锰锌的防效。综合病叶(果)率、病情指数及防效,波尔多液、戊唑醇、氟硅唑是控制红乳葡萄黑痘病的理想药剂。更多还原

【Abstract】 Control efficiency of six fungicides on anthracnose fungus of red nipple grape under rain-sheltered cultivation vs.open field cultivation was investigated.The results showed that all the six fungicides showed satisfactory effects on the control of anthracnose fungus disease of leaves(90.4%) and fruits(97.8%) of red nipple grape under rain-sheltered cultivation.Significant difference was observed on the control effects of the six fungicides on the disease of the grapes under open-field cultivation,and 80% of bordeaux mixture,25% of tebuconazole and 40% of flusilazole showed a significantly higher control effect than did 40% of carbendazim,75% of chlorothalonil and 80% of mamcozeb.Bordeaux mixture,tebuconazole and flusilazole are the best fungicides for the control of anthracnose disease of red nipple grape.更多还原
