Résumé
In order to evaluate the real situation of the main citrus graft-transmissible pathogens in Iraq, a wide survey was carried out in Baghdad region, considered to be the most important citrus- growing area in the country. More than 1000 citrus trees belonging to 3 commercial orchards and 1 nursery located in this region were individually inspected for symptom expression ; 300 samples, in the material collected, were also processed for biological, serological and molecular tests. Fortunately neither CTV nor Candidatus Liberibacter asiaticus infectious agents, which pose today a major threat to the citrus industry worldwide, were reported in the surveyed citrus areas. However, this survey confirmed the wide distribution of S. citri in both commercial orchards and nurseries and allowed reporting for the first time the presence of citrus infectious pathogens such as CPsV, CEVd and HSVd from the most important Iraqi citrus-growing area.
