The PULVEDRONE project assessed the quality of drone spraying over 3 years of trials from 2019 to 2021 (Ardèche, France).
Following the ban on aerial spraying in 2015, crop-protection spraying of steeply sloping vineyards is mainly carried out by workers on the ground, who are subject to arduous working conditions, increased risk of exposure to sprays, as well as the risk of accidents (overturning of machinery). Drones (UAV, Unmanned Aerial Vehicles) could provide an alternative to ground spraying of plots that are inaccessible to machinery.
