Pierluigi Bonello of Ohio State University in the U.S. will develop a surveillance system for crops using unmanned aerial vehicles (drones) to position sensors to help diagnose plant diseases in low-income countries. Plant diseases are usually identified first by the farmers or human scouts and then confirmed by laboratory testing. This process is inefficient and requires resources often unavailable in low-income countries, calling for alternative approaches. It is known that when a plant becomes infected, it produces specific chemicals.
