Control Efficacy of Different Fungicides Against Wheat Leaf Rust
-
摘要: 小麦叶锈病是我国小麦生产上的重要病害之一,每年给小麦产业造成严重的危害.目前,化学药剂防治仍是控制小麦叶锈病大流行的主要手段和措施.因此,本文通过田间小区试验比较了10种市售杀菌剂对小麦叶锈病的防治效果,以筛选对小麦叶锈病有较好防效的药剂.试验结果表明,环丙唑醇、烯唑醇、氟环唑、戊唑醇、肟菌·戊唑醇、啶氧·丙环唑和吡唑醚菌酯等对小麦叶锈病均有较好的防控效果,防效可达80%以上.其中,以环丙唑醇、烯唑醇、氟环唑和戊唑醇在防病效果更为高效,表现为用量少、防效高.研究结果旨在为田间小麦叶锈病的防控提供依据.Abstract: Field trials were carried out in this study to determine the control efficacy of ten fungicides against wheat leaf rust,in order to provide a reliable reference to the future control of wheat leaf rust. The results showed that the fungicides cyproconazole,diniconazole,epoxiconazole,tebuconazole,triximium pentazolol,idioxypropionazole and pyraclostrobin could effectively control the wheat leaf rust with a control efficiency over 80%,and of the seven,cyproconazole,epoxiconazole and tebuconazole performed most satisfactorily,with a lower dose and higher control efficacy.
