摘　　要：通过小区试验,评估了40%噻唑锌悬浮剂、40%春雷·噻唑锌悬浮剂、3%噻霉酮微乳剂、5%噻霉酮悬浮剂等4种杀菌剂对水稻细菌性条斑病的防治效果。小区试验结果显示,40%噻唑锌悬浮剂750 mL/hm^(2)处理的防效在85%以上,优于其他3种药剂处理。同时,采用大面积示范试验,探究了40%噻唑锌悬浮剂采用植保无人机喷施的防效。示范试验结果显示,飞行参数为高度3 m、速度7.5~8 m/s、行距6.5~7 m时,40%噻唑锌悬浮剂750 mL/hm^(2)处理的防效为83.29%~86.61%,飞防施药能够避免因常规农事操作引发的病害传播。该研究对40%噻唑锌悬浮剂采用植保无人机施药防治水稻细菌性条斑病具有指导作用。The control efficiencies of four fungicides,including zinc thiazole 40%SC,kasugamycin·zinc thiazole 40%SC,benzisothiazolinone 3%ME and benzisothiazolinone 5%SC,on rice bacterial leaf streak were evaluated by plot trials.The results showed that the control effects of zinc thiazole 40%SC were above 85%at the dosage of 750 mL/hm^(2),which was better than those of the other fungicides.Then,the demonstration tests were carried out to explore the control effects of zinc thiazole 40%SC by plant-protection unmanned aerial vehicle.At the flight height of 3 m,speed of 7.5-8 m/s and row spacing of 6.5-7 m,the control efficiencies of zinc thiazole 40%SC 750 mL/hm^(2)were 83.29%-86.61%,and spraying by plant-protection unmanned aerial vehicle could avoid the spread of diseases caused by conventional farming operations.The study could provide guidances on the application of zinc thiazole 40%SC aganist rice bacterial leaf streak by plant-protection unmanned aerial vehicle.
