摘要

在田间测定了13种杀菌剂对小麦黑胚病的防治效果.结果表明,13种杀菌剂对小麦黑胚病均有一定的防效,防效为34.8％～67.7％.其中7.5％氟环唑乳油50 g/hm2、50％嘧菌环胺水分散粒剂 375 g/hm2、56％嘧菌·百菌清悬浮剂330 g/hm2、25％丙环唑乳油180 g/hm24个处理对小麦黑胚病有较好的防治效果,防效均达到60％以上,可在生产中推广应用.%The control efficacy of 13 fungicides on the wheat black point disease were tested in the field. The results showed that 4 fungicides had better control efficacy to black point disease, including epoxiconazole 7.5% EC, cyprodinil 50% WG.chlorothalonil&azoxystrobin 56% SC and propiconazole 25% EC. All of them could get a better preventive efficacy of over 60%, which was recommended for wheat production.
