摘　　要：为筛选出适合刺梨病虫害防治采用的高效低耗新型植保喷雾器械,本研究比较了手动喷雾器、电动喷雾器、汽油喷雾器以及植保无人机等4种植保喷雾器械喷施30%吡唑醚菌酯悬浮剂对刺梨白粉病的田间防控效果,及4种植保喷雾器械的作业效率和作业成本。研究结果表明,4种喷雾器械在施药后7和14 d的防控效果均>80%。在喷雾器械工作效率方面,无人机作业效率最高,手动喷雾器作业效率最低。在喷雾器械作业成本方面,电动喷雾器成本最低为345元/hm2,手动喷雾器作业成本最高,为495元/hm2。本研究结果为刺梨病虫害防控喷雾器械的选择提供了科学指导。This study aimed to identify an effective sprayer for controlling powdery mildew on Rosa Roxburghii Tratt by comparing four types of sprayers in field conditions.The manual sprayer,electric sprayer,gasoline sprayer and plant protection drone were evaluated in terms of control efficacy,work efficiency and cost,using pyraclostrobin 30%WP as the pesticide.The results showed that pyraclostrobin 30%WP effectively controlled powdery mildew,achieving 80% efficacy after 7 days and 14 days with all four types of sprayers.The plant protection drone exhibited the highest efficiency,while the manual sprayer performed the least.The electric sprayer had the lowest cost at 345 yuan/hm2of,whereas the gasoline sprayer incurred the highest cost at 469 yuan/hm2of.The results of this study provide scientific guidance for selecting appropriate spraying equipment for pest control on Rosa Roxburghii Tratt.
