Article Synopsis
- Achieving the right droplet size for aerial spraying using unmanned aerial spray systems (UASSs) is challenging due to weight and pressure limitations.
- A study calibrated a UASS to produce droplet sizes of 48 µm for effective dispersal at a height of 23 m, confirming a spray pattern and effective ground coverage over significant distances.
- Results showed a 13-36% ground deposition of the sprayed material, suggesting aerial adulticiding is viable, but further improvements in atomization techniques and altitude effects on droplet size are needed for operational efficiency.

Achieving an appropriate droplet size distribution for adulticiding has proved problematic for unmanned aerial spray systems (UASSs). The high-pressure pumping systems utilized on crewed aircraft conflict with the weight constraints of UASSs. The alternative is a lightweight rotary atomizer, which when run at a maximum rpm with a minimal flow rate can achieve the appropriate droplet size distribution.

The atomization characteristics of 4 handheld sprayers (Leco P-1, Colt ULV Aerosol Generator, ULVAFAN MK2, Turbair ElectraFan 12) and a Stih1 SR400 backpack sprayer were evaluated with the use of water- and oil-based solutions. The effects on droplet-size spectrum (i.e.
