Development and Implementation of an Ultra-Low Volume (ULV) Spraying Equipment Installed on a Commercial UAV

The aerial pesticide application assumes remarkable weightiness, especially in agricultural contexts, characterized by immediate interventions hardly executable through the traditional spraying techniques. The Unmanned Aerial Vehicles are versatile and easy to manage technology, capable to perform pesticide application on small and hardly attainable land parcels thanks to a specific crop spraying system. The opportunity to plan automatic flights allows performing an accurate application, optimize the quantity of pesticide applied and limit the contact between the operator and the toxic product. The objective of work was to develop a small pesticide spraying system (<1 kg weight payload), with the purpose to install it on board of a commercial drone, Phantom 4 pro DJI© (with a maximum payload of 3.0 kg), in order to demonstrate his potential for manage commercial bio-pesticide on horticultural crops.
