摘　　要：2022—2023年,在淮安市洪泽区进行小麦赤霉病自动监测预警系统的试验示范,并以监测预警系统的预测结果为指导开展田间药剂复配试验,以期确定最佳的喷施次数、药剂组合和药剂用量,指导大田小麦赤霉病的防控。结果表明,200 g/L氟唑菌酰羟胺悬浮剂(麦甜)900 mL/hm^(2)+250 g/L丙环唑乳油(麦甜伴侣)600 mL/hm^(2)+22%噻虫·高氯氟微囊悬浮-悬浮剂150 mL/hm^(2)+益施多金750 mL/hm^(2)二次施药是防治小麦赤霉病的最优药剂组合与用量,对小麦赤霉病的病指防效达到85.28%。The experimental demonstration of automatic monitoring and warning system for Fusarium head blight(FHB)was carried out in Hongze District of Huai'an City from 2022 to 2023.Based on the prediction results of the monitoring and warning system,field fungicides compound experiments were conducted to determine the optimal spraying frequency,fungicide combinations and dosage,and to guide the prevention and control of FHB in the field.The results showed that 200 g/L pydiflumetofen SC(Maitian)900 mL/hm^(2)+250 g/L propiconazole EC(Maitian Banlyu)600 mL/hm^(2)+22%thiamethoxam·efficient cyhalothrin ZC 150 mL/hm^(2)+Yishi Duojin 750 mL/hm^(2)(spraying twice)was the best combination and dosage to control FHB,and the disease index control efficacy on FHB reached 85.28%.
