The plant epidemic that is causing the so-called CoDiRO or Rapid Complex Desiccation of Olive Trees in Salento (Apulia) was, without doubt, caused by the Xylella fastidiosa bacterium. This is the conclusion, reached by the European Food Safety Authority (EFSA), on the basis of research conducted on its behalf by the National Research Centre (CNR) and by the Basile Caramia Research Center in Locorotondo (Bari).
Researchers exposed varieties of major perennial crops to the bacterium through artificial inoculation and by exposure to infective insect vectors in the field. Not only olive trees were tested but also other Mediterranean plants such as grape, citrus, almond, peach, cherry and plum, forest species such as holm oak and ornamental species such as oleander and myrtle-leaf milkwort.
