Mid-Columbia Agricultural Research and Extension Center is working on a pair of projects researching the use of drones in orchards.  One area involves pesticide application.  Faculty Research Assistant Niall Millar says they just completed a trial of spray coverage from a drone.  He says the concept is to provide improve the effectiveness of an application for the top of tree.  Miller says another area being studied is using drones with a hyperspectral camera to detect X disease much earlier than can be done now.
