Photo of cover of publication, Pierce's Disease.

UC plant pathologists believe that the bacterium that causes Pierce's disease in grapes, Xylella fastidiosa, is probably in every county in the state of California where grapes are grown. Find out what you can do to combat this major threat to the grape industry.

This new publication covers the symptoms of Pierce's disease and offers strategies for management. Included is a description of Pierce's disease incidence in the various grape growing regions of California; descriptions of the four major insect vectors that spread the disease causing bacterium Xylella fastidiosa; and the role that alternative host plants play as a reservoir of the bacteria. Also included is information on the pattern of spread in vineyards by the different vectors; how to monitor the vectors; and a description of management strategies you can use in your vineyard.
