Absence of Xylella fastidiosa in Jordan

Official surveys have been conducted in Jordan from 2016 to 2021 to assess the possible presence of Xylella fastidiosa (EPPO A2 List), as well as its potential vectors.

Plant samples were collected from the different regions of Jordan. Approximately 899 grapevines (Vitis vinifera) were sampled from 378 fields, 1480 stone fruit trees (Prunus armeniaca, P. avium, P. cerasifera, P. domestica, P. dulcis, P. mahaleb, and P. persica) were sampled from 596 fields, 1225 citrus fruit trees (Citrus clementina, C. limon, C. maxima, C. paradisi, C. reticulata, and C. sinensis) were sampled from 415 fields, 292 pome fruit trees (Cydonia oblonga, Eriobotrya japonica, Malus domestica, and Pyrus calleryana) were sampled from 114 fields, and 1351 ornamental plants were sampled from 954 distinct places covering all fruit-tree-growing regions in Jordan. 

For olive (Olea europaea), the official surveys were conducted in 2018-2019 in all olive-growing regions of Jordan. A total of 975 commercial and non-commercial olive orchards were inspected for the presence of typical symptoms of X. fastidiosa and sampled. 

All samples tested negative.

The situation of Xylella fastidiosa in Jordan can be described as: Absent, confirmed by survey.
