不同植保无人机对小麦赤霉病的防控效果

Study on the Prevention and Control Effects of Different Plant Protection UAVs in the Control of Wheat Scab

为研究不同植保无人机在小麦赤霉病防治中的防控效果以及安全性,通过多种植保无人机和大机械喷雾2种不同施药方式开展药效试验。结果表明,极飞P20、极飞P30、大疆T16、大疆T20植保无人机喷施常规药剂均对小麦安全,综合防效较好,病穗率防效分别为74.56%、73.11%、78.74%、73.26%,病指防效分别为84.86%、79.36%、87.02%、84.31%;植保无人机处理与大机械处理之间无显著性差异。

The objective of the current research was to study different unmanned aerial vehicles(UAVs)for plant protection regarding their effect of preventing and controlling wheat head blightand their safety.A field trial was carried out to determine the control efficacy of two different methods of applying commonly used fungicides:different plant protection UAVs,and the conventional application method of using a self-propelled sprayer.The results showed that spraying the fungicides by the plant protection UAVs XAIRCRAFT P20,XAIRCRAFT P30,DJI T16,and DJI T20 was safe for wheat and also achieved overall high control efficacy.XAIRCRAFT P20,XAIRCRAFT P30,DJI T16,and DJI T20 attained the control efficacy of 74.56%,73.11%,78.74%,and 73.26%,respectively,based on the rate of diseased ears;and achieved the control efficacy of 84.86%,79.36%,87.02%,and 84.31%,respectively,based on ear disease index.There was no significant difference in control efficacy between the plant protection UAV treatments and the control treatment of the self-propelled sprayer.
