The study tested the effect of different flight and spraying parameters of the commercial unmanned aerial vehicles (UAVs) DJI Agras T10 and T50 on spray downwash. The aim was to enable precision spray path planning by analysing the spatial spray distribution and swaths produced by the UAVs. The results showed an inhomogeneous droplet density distribution along the spray swath. The droplet distribution showed higher droplet density below the rotor-nozzle lines, highlighting the presence of two peaks. The higher forward speeds (4 and 5.6 m/s) and higher flight altitudes (2.5 and 3 m) reduced the peaks intensity and produced a more uniform spray swath. The average spray swath of the Agras T50 platform was slightly wider (3.5–4.5 m) than that of the Agras T10 (2.5–3.5 m), depending on the different flight and spraying parameters.
