• Abstract: Several diseases of agronomic, horticultural, and landscape ornamental plants in California are caused by Xylella fastidiosa (Xf) (Purcell and Hopkins, 1996, Purcell et al. 1999). Effective disease management strategies are dependent upon knowledge of inoculum sources, biology and ecology of Xf insect vectors (e.g., glassy-winged sharpshooter [GWSS]) and natural enemies, and characteristics of disease progress. In the short term, commercially available materials may be useful in vineyards to reduce Xf transmission by the GWSS (e.g., Surround, containing 95% Kaolin), and to prevent Xf infection of grapevines and Pierces disease (PD) development (e.g., systemic acquired resistance inducers, such as Messenger, containing 3% harpin).
