1. The Evolution of Orchard Spraying Technologies
   1.1 Traditional Challenges in Fruit Tree Management
   Manual and ground-based pesticide application methods face persistent issues:

• Labor shortages due to urbanization and aging rural populations.
• Inconsistent coverage caused by uneven terrain or dense foliage.
• High chemical waste from wind drift or overlapping spray patterns.
• Health risks to workers exposed to toxic substances. 1.2 How Orchard Spraying Drones Fill the Gap
  Orchard spraying drones integrate robotics, AI, and agricultural science to overcome these limitations. Unlike conventional drones, they are engineered with:
• Multi-rotor or fixed-wing designs for stability in windy orchard environments.
• Obstacle avoidance systems to navigate complex tree canopies.
• Variable payload capacities (5–30 liters) tailored to farm size and crop needs.
