摘要
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/hm^(2)、250 g/L丙环唑乳油112.5 g/hm^(2)及250 g/L吡唑醚菌酯油112.5 g/hm^(2)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/hm^(2)和250 g/L丙环唑乳油112.5 g/hm^(2)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/hm^(2),112.5 g/hm^(2),112.5 g/hm^(2),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/hm^(2)),propiconazole 250 g/L EC(112.5 g/hm^(2))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.
