Japan develops a drone to patrol farmland and destroy insect pests
They developed the Agri Drone to reduce the use of pesticides through the application of drones. Primarily used at night, it utilises infrared and thermal cameras to shoot targeted doses of pesticides where insects are congregating in harmful numbers. As it's a targeted shot, the idea is the drone greatly reduces plants' over-exposure to pesticide.
The Agri Drone has recently been successfully put through its paces in test runs, guarding both soy and potato crops in the Saga prefecture. It was successful in seeking out and destroying 50 different types of pest, including midges and moths.
If spraying chemicals is something that farmers wish to avoid, the Agri Drone comes with another option in tackling insects in the form of a suspended bug zapper. The drone can be assigned the task of delivering a glowing, insect-enticing electric payload to the points at which the pests are congregating.
