A bacterial disease of grapevines (Xylella fastidiosa) spread by sharpshooter insects that blocks water conducting tissue, causing leaf scorch, fruit shrivel and vine death, typically within one to five years of infection. Native to the Americas, it devastated vineyards in Southern California in the nineteenth century and remains a limiting factor on winegrape production across the southern and southeastern United States, and related strains of the same bacterium threaten olive groves in Europe.
