The UAV downwash airflow pattern generated by rotor propellers is one of the significant factors influencing the characteristics of spray droplet deposition distribution. UAV sprayer and battery operated sprayer were used to study the effect of downwash airflow distribution of UAV on spray droplet deposition characteristics in a paddy field. The UAV sprayer was operated with optimized operational parameters and spray droplet characteristics, viz. spray deposition rate (µl cm–2), spray droplet size (µm), spray deposition density (No’s cm–2) and spray deposition uniformity (%) were analysed using Deposit Scan software. The UAV sprayer showed better results in spray droplet deposition rate, spray coverage per unit area and spray droplet deposition densities than the conventional battery-operated manual sprayer. Additionally, it was found that the UAV sprayer increased the chemical’s penetration into crop leaves, leading to higher chemical deposition on both the upper and lower layers of rice leaves.Keywords
