Olive quick decline syndrome (OQDS) 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.[1]
The disease affected olive groves in Southern Italy where it is known as CoDiRo which is short for Complesso da Disseccamento Rapido dell'Olivo (CDRO).
Symptoms include leaf scorch and desiccation of twigs and branches, beginning at the upper part of the crown and then moving to the rest of the tree, which acquires a burned look[2].
