A new publication from the UGA team on bacterial streak and bulb rot of onion: bacterial streak and bulb rot of onion has been a problem in onion-growing regions of Georgia, USA since 1990. This disease can be a major limiting factor in onion production in other parts of the world. Weed species have been shown to serve as important inoculum sources for P. viridiflava (Gitaitis et al. 1998).
