    Sprayer drones for rust control

    Traditional methods of spray applications involve extensive PPE, water use and labor time. Drones can be used instead of actual employees in the field to reduce the risk of exposure, the need for extensive and uncomfortable PPE, and water use for dilution. We set out to look at the efficacy of drone spray applications against traditional methods, such as an airblast sprayer for the control of gymnosporangium rust on Amelanchier.
