UGA researchers develop technology to prevent spread of onion diseases

Dr. Changying (Charlie) Li with device that detects the gas given off by rotting onions.Onions, one of the biggest vegetable crops in Georgia, risk disease when they are harvested and stored. To solve this issue, University of Georgia researchers have developed new technologies, including a gas sensor and imaging methods, to detect diseases in onions.

Their study was published recently in the journal Sensors.

As part of a three-year grant, Changying “Charlie” Li, an associate professor in the College of Engineering, sought to find latent diseases in onions, ones not easily detected by the human eye. These diseases can spread to other onions in close vicinity, sometimes damaging half of the supply in storage.
