A bacterial disease, caused by the same bacterium, Xylella fastidiosa, that causes Pierce's disease of grapevines in a distinct subspecies and host range, first identified killing olive trees in the Salento peninsula of southern Italy in 2013 by blocking water-conducting tissue and causing severe leaf scorch, branch dieback and eventual tree death, with no cure once a tree is infected. It has since been found in Corsica, mainland France and Spain, and because its spittlebug vectors are widespread and no eradication method exists for a mature infected tree, the European Union has imposed strict removal and buffer zone requirements in affected areas to slow its spread toward the wider Mediterranean olive belt.

Wikimedia FoundationOpening definition paragraph
Olive quick decline syndrome is a wasting disease of olive trees which causes dieback of the leaves, twigs and branches so that the trees no longer produce crops of olives. The main cause is a strain of the bacterium, Xylella fastidiosa, which is spread by plant-sucking insects such as the meadow froghopper. The bacteria restrict the flow of sap within the tree and so choke its extremities.
