Transforming Agriculture: The Power
​of Agricultural Spray Drones

In recent years, the agricultural sector has witnessed a technological revolution through the introduction of agricultural spray drones. These unmanned aerial vehicles (UAVs) are reshaping how farmers manage their crops, offering efficiency, precision, and cost-effectiveness in various agricultural tasks. From mini helicopters powered by gasoline to battery-operated multi-rotor UAVs, these drones are revolutionizing farming practices worldwide.

Mini Helicopters

Originating in Japan and pioneered by Yamaha Motor Company, mini helicopters like RMAX, Fazer, and Fazer-R have paved the way for precise aerial spraying. These two-bladed rotor aircraft are powered by water-cooled gasoline engines and are remotely operated through line-of-sight control. Initially designed for accurate crop spraying, they now also serve aerial surveys, reconnaissance, and disaster response.

A remarkable feature is their payload capacity, carrying 16 to 32 kg of spray material. With an hour-long flight time, they cover extensive agricultural landscapes efficiently.

Multi-Rotor UAVs

China has emerged as a hub for multi-rotor UAV development, with the DGI AGRAS MG-1 leading the pack. Sporting eight rotors and a 13.7 kg payload capacity, the AGRAS operates on battery power. Though it has a shorter flight time compared to helicopters, it has gained global popularity among contract sprayers.

Another approach is seen with Thea 140, a 4-rotor UAV featuring a 10-liter payload and a hybrid power system. China offers a variety of 4 and 6-rotor battery-operated spray UAVs with payloads of 7 to 10 liters. These drones offer flight times of 12-15 minutes and are mainly used in the Chinese market.
The US has also entered the arena with UAVs like the HSE M6A Pro 15. This 6-rotor UAV shares specifications with the DGI AGRAS MG-1, highlighting a worldwide push to harness the potential of agricultural spray drones.

Heavy-Lifting UAVs

Heavy-lifting UAVs are making exciting strides. The Carrier HX-8, with a capacity of 20 liters, is on the brink of entering the market. Meanwhile, the Airboard Agro 100 from Latvia and the Tactical Robotics Cormorant from Israel signify significant advancements, boasting capacities of 100 and 500 liters, respectively. While the Cormorant was initially designed for delivery and rescue, its adaptation for spraying will require regulatory adjustments.
​
The evolution of agricultural spray drones signifies a transformative shift in modern farming. As technology advances and regulations adapt, these drones are poised to redefine agricultural practices worldwide, offering precision, efficiency, and sustainability to farmers.
