Unmanned aerial vehicle (UAV) sprayers have been widely used in agriculture. With the goals of using pesticides efficiently and reducing their dosage, we evaluated the effects of adding and not adding special adjuvants to UAV sprayers on droplet deposition and the control effect of leaf folder insects. The deposition quantity and coverage area of UAV sprayers with the Kao Adjuvant A-200® on rice leaves were better than those without the Kao Adjuvant A-200®. Regarding the control effect on rice leaf rollers, UAV sprayers with the Kao Adjuvant A-200® were also better, and they also met the pesticide residue limit for brown rice. Kao Adjuvant A-200® can improve the UAV sprayer's droplet deposition and pest control effect. When the pesticide dosage was reduced by 30%, UAV sprayers with Kao Adjuvant A-200® can achieve a good control effect, which is very helpful in reducing the pesticide dosage.
无人机喷雾器已在农业中广泛应用。为了高效使用农药并减少其用量，我们评估了无人机喷雾器添加和不添加特殊助剂对液滴沉积以及稻纵卷叶螟防治效果的影响。配备高田助剂A - 200®的无人机喷雾器在水稻叶片上的沉积量和覆盖面积优于未添加高田助剂A - 200®的情况。在对稻纵卷叶螟的防治效果方面，配备高田助剂A - 200®的无人机喷雾器同样表现更好，且它们也符合糙米的农药残留限量标准。高田助剂A - 200®能够提高无人机喷雾器的液滴沉积和害虫防治效果。当农药用量减少30%时，配备高田助剂A - 200®的无人机喷雾器仍能达到良好的防治效果，这对于减少农药用量非常有帮助。
