Low pesticide utilization, particularly in high-concentration aerial spraying via an unmanned vehicle (UAV), poses a severe risk terms of waste and environmental damage. We conducted new trial to improve the properties spray liquid by addition customized adjuvants, thereby facilitating droplet deposition reducing drift UAV-sprayed pesticides. Our self-developed mango tree special diffusing agent (PDA) altered both value components surface tension toward that leaf free energy; thereby, apparently contact angles droplets on more than 70.00%. The retention ability (Rmax) diluents was enhanced 0.75-1.24 times, but no injury induced. Moreover, PDA endowed with strong anti-drift performance under ambient temperature humidity levels typical tropical areas, substantially decreased cumulative rate 31.09-67.08%. buffer zone distance shortened from 8.19-8.62 m around 4.61-5.79 m. Customized development adjuvant based canopy surface, together operation characteristics UAV sprayers, efficient way achieve optimization solution system promoting its targeting delivery crop surface. findings provide inspiration references for selection, application increase efficiency curb agricultural non-point source pollution. © 2025 Society Chemical Industry.
