Pierce's disease

noun

ˈpir-səz-

: a disease of grapes that is caused by a bacterium (Xylella fastidiosa fastidiosa) which blocks the flow of xylem, that is marked especially by yellowing and browning of the leaves, leaf loss, shriveling of fruit clusters, stunted and irregular new growth, and eventual death of the vines within one to five years, and that is spread by sap-feeding leafhoppers and spittlebugs

Carried by an insect, Pierce's disease affects grapevines much like a severe drought condition, causing the grapevines to eventually shut down from lack of moisture.

Robyn Bullard

Pierce's disease is most prevalent in mild-winter areas and is the principal factor limiting European grapevine cultivation in the American South.
