DETECTING HUANGLONGBING (HLB) IN CITRUS PLANTS BY ANALYZING CHANGES IN EMITTED VOLATILE ORGANIC COMPOUNDS

摘要

The disclosed embodiments relate to a technique for detecting Huanglongbing (HLB) infection in a citrus plant. This technique involves first gathering one or more samples of volatile organic compounds (VOCs) emanating from the citrus plant. Next, a system measures VOCs in the gathered samples to determine a VOC profile for the citrus plant, wherein the VOC profile comprises measured values for a set of VOCs that comprise disease-specific biomarkers for HLB infection. Finally, the system determines an HLB infection status for the citrus plant by analyzing the VOC profile.
