About Pierce's Disease
Pierce's Disease is a deadly disease of grapevines. It is caused by the bacterium Xylella fastidiosa, which is spread by xylem feeding leafhoppers known as sharpshooters.
Pierce's Disease is known to be prevalent within the USA from Florida to California, and outside the USA in Central and South America. Xylella fastidiosa works by blocking
the xylem, which conducts the water around the plant. Symptoms include chlorosis and scorching of leaves, and entire vines will die after 1-5 years. Pierce's Disease
is less prevalent where winter temperatures are cold, such as more northern areas, high altitudes and inland areas.
