Spray drift evaluation from a four-axis unmanned aerial spraying system: effects of spray parameters under different wind speeds and comparison with a boom sprayer.

Key Points

• The aim is to assess how different spray parameters affect drift behavior in unmanned aerial spraying systems (UASS) under varying wind conditions.
• Evaluated drift behavior of UASS across different wind speeds
• Analyzed effects of spray parameters on drift
• Compared UASS performance with that of a traditional boom sprayer
• Identified specific parameters that significantly reduce drift under high wind conditions
• Found that UASS can optimize pesticide application compared to boom sprayers
• Provided quantitative data to support parameter adjustments for safer applications
