摘　　要：为筛选出防治小麦赤霉病及白粉病的高效低毒杀菌剂,在小麦扬花初期和扬花盛期施药开展小麦赤霉病、白粉病及增产效果的田间试验。结果表明:在小麦扬花初期和扬花盛期施药,15%丙唑·戊唑醇悬浮剂(60 mL/667 m^(2))、480 g/L丙硫菌唑悬浮剂(20 mL/667 m^(2))对小麦赤霉病、白粉病防治效果较好。15%丙唑·戊唑醇悬浮剂(60 mL/667 m^(2))加入植物生长调节剂和叶面肥(0.1%S-诱抗素25 g/667 m^(2)+含氨基酸水溶肥40 g/667 m^(2)+磷酸二氢钾30 g/667 m^(2))后,增产效果明显。To identify high-efficiency and low-toxicity pesticides for controlling wheat fusarium head blight and powdery mildew,field experiments were conducted during the early and peak flowering stages of wheat to evaluate disease control and yield improvement.The results indicated that applying 15% propiconazole tebuconazole SC(60 mL/acre)and 480 g/L propiconazole SC(20 mL/acre)during these stages exhibited effective control over wheat fusarium head blight and powdery mildew.Adding plant growth regulators and foliar fertilizers(0.1%S-inducer 25 g/acre+amino acid watersoluble fertilizer 40 g/acre+potassium dihydrogen phosphate 30 g/acre)to 15% propiconazole·tebuconazole SC(60 mL/acre)resulted in a significant yield increase.
