A bacterium that lives in the water conducting system (xylem) of plants
Grapevines show symptoms of water stress, such as leaf scorch, and the plant progressively weakens and dies
Can be transmitted in infected propagation material and by leafhoppers such as the exotic glassy-winged sharpshooter
Present in North America, Central America and some regions of South America. It is present in a restricted range in Italy, Iran and Taiwan, and is under eradication in some other countries in Europe. View a distribution map.
The diseases caused by Xylella fastidiosa go by a range of names depending on the host species, including: Pierce’s disease, almond leaf scorch, bacterial leaf scorch, citrus variegated chlorosis, olive quick decline and olive leaf scorch.
