What is Pierce's Disease?

Pierce’s Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

  • ROLE OF ALFALFA IN THE EPIDEMIOLOGY OF XYLELLA FASTIDIOSA IN CALIFORNIA
    Alfalfa occurs widely throughout the Central Valley, often adjacent to grape and other plants susceptible to Xylella fastidiosa (Xf). A previous epidemic of Pierces disease in the Central Valley was associated with migration of infective insects from alfalfa fields to vineyards. We will determine the importance of alfalfa as a host of different strains of Xf and its role as a source of the pathogen for vector transmission. These studies provide basic information on these interactions, which would be incorporated in disease management strategies that include alfalfa as a host of Xf and sharpshooter vectors.
