2019 — 2020年，田间试验观测了8种杀菌剂对小麦条锈病的防治效果。结果表明，125 g/L氟环唑悬浮剂56.25 g/hm2、250 g/L丙环唑乳油112.5 g/hm2及250 g/L吡唑醚菌酯油112.5 g/hm2的推荐使用剂量对小麦条锈病的防效均达80%以上，其中氟环唑3次调查的防效分别为91.80%、93.57%、88.61%。与清水对照相比，8种杀菌剂处理后小麦产量均增加，125 g/L中氟环唑悬浮剂56.25 g/hm2和250 g/L丙环唑乳油112.5 g/hm2处理增产效果最明显，增产率分别为25.38%和21.56%，可大面积应用。

The field trials were conducted to observe the control effect of eight fungicides against wheat stripe rust from 2019 to 2020. The result showed that epoxiconazole 125 g/L SC， propiconazole 250 g/L EC，pyraclostrobin 250 g/L EC cnotrol effect were all above eighty percent when the treatment concentrations were 56.25 g/hm2， 112.5 g/hm2， 112.5 g/hm2， respectively， and the epoxiconazole 125 g/L SC three survey control effect were 91.80%， 93.57%， 88.61%. Compare with water control， all wheat yield were increased by treat with 8 fungicide treatment， espcially epoxiconazole 125 g/L SC (56.25 g/hm2)， propiconazole 250 g/L EC (112.5 g/hm2) treatment had the most obvious effect on increasing wheat yield， and the increase rates of yield were 25.38%and 21.56%， respectively， which could be applied in a large area.
