摘　　要：为了明确生产上常用的6种杀菌剂对小麦叶锈病的防治效果及产量的影响,2019—2020年在漯河市农业科学院试验基地进行药剂防治试验。结果表明,在小麦叶锈病发病初期施药,药后29 d,200 g/L氟唑菌酰羟胺+25%丙环唑对小麦叶锈病的防效最高,达83.86%,其次是40%丙硫·戊唑醇,防效为79.27%;200 g/L氟唑菌酰羟胺+25%丙环唑对小麦的增产效果最为明显,比对照增产14.09%。该地区防治小麦叶锈病,最佳配方为200 g/L氟唑菌酰羟胺+25%丙环唑,不仅有很好的防治效果,同时可显著提高小麦产量。In order to find out the control effect of six fungicides on wheat leaf rust and their effect on yield,the experiment of fungicide control was carried out in the experimental base of Luohe Academy of Agricultural Sciences from 2019 to 2020.The results showed that the control effect of 200 g/L fluconazole and 25%propiconazole was 83.86%,the control effect of 40%compounded agent containing propiconazole and tebuconazole was 79.27%;the yield increasing effect of 200 g/L fluconazole and 25%propiconazole was the most obvious,reaching 14.09%.The best formulation was 200 g/L fluconazole and 25%propiconazole,which not only had good control effect,but also increased wheat yield.
