Agricultural spraying drones are designed to apply pesticides, herbicides or fertilizers directly to the fields. They use GPS navigation and sensors to precisely cover the required area, saving chemicals and water and reducing environmental impact. Leading manufacturers include DJI (Agras series), Rather, Yamaha and Hylio. The payload of the tanks depends on the model – smaller drones can carry 10–15 kg of spray mixture, while the largest professional machines can handle 40–50 kg per flight cycle.
