以甬优12为材料,进行了水稻白叶枯病不同器械施药防效试验。结果表明,选用相同药剂和药量（20%噻唑锌悬浮剂125 mL/667 m²）,用植保无人机飞防施药对白叶枯病的防效达84.36%,极显著优于用担架式喷雾机或背负式智能电动喷雾器施药,且安全性好。植保无人机施药在水稻生产上具有良好的推广应用前景。文章小结和讨论了无人机飞防白叶枯病新技术。

A test of the control effects of different equipments on rice bacterial blight was carried out with the variety Yongyou 12 as the material. The results showed that under the same agent and application rate （20% zinc thiazole SC, 125 mL/667 m²）, the anti-bacterial blight control effect of UAV reached 84.36%, which was significantly better than using stretcher sprayer or knapsack intelligent electric sprayer for spraying, and the safety was good. UAV has good application prospects in rice production. The article summarized the new technology of UAV flight prevention against bacterial blight.
