8种杀菌剂对小麦条锈病的田间防效
Gansu Agricultural Science and Technology(2021)
Abstract
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.
