First report of plum pox potyvirus in Jordan
In Jordan, a survey for virus diseases of stone fruits was carried out in 51 commercial orchards, 7 private gardens and 4 varietal collections. In total, 1312 Prunus trees (almond, apricot, cherry, peach, plum) were tested for the presence of plum pox potyvirus (PPV – EPPO A2 quarantine pest). PPV was detected in 7 trees (3 peaches, 2 plums and 2 apricots). All strains found in Jordan belonged to PPV-M. No evidence of active spread of the virus in the field was noted. Although infected trees were few and scattered, it is stressed that they constituted highly dangerous inoculum sources which should be rapidly eliminated. This is the first report of plum pox potyvirus in Jordan. The situation of this virus in Jordan can be described as: Present, at low prevalence.
