Plant Aid: A Big-Data Project to Detect Plant Diseases Faster

An interdisciplinary team led by professor Jean Ristaino will combine small sensors with big data for faster detection of the diseases plaguing tomato fields. From a hand-held plant disease ‘sniffer’ to a cloud-based database that can alert farmers about the cause of the stress and suggest possible mitigation strategies, the project aims to detect diseases early, improving yield.
