First finding of Plum pox virus in Pakistan
In Pakistan, several apricot trees (Prunus armeniaca) showing virus symptoms were observed in a small orchard in the Baltistan District (north of Pakistan) located at an altitude of 2400 m. Dried leaf samples taken from one symptomatic tree were tested (ELISA) for the presence of Plum pox virus (Potyvirus, PPV – EPPO A2 List) and gave positive results. Molecular studies showed that two different PPV isolates were present: PPV-D and PPV-Rec. Further studies are needed to better understand the situation of PPV in Pakistan, but this is the first indication that PPV occurs in this country.
The situation of Plum pox virus in Pakistan can be described as follows: Probably present, first detected in 2006 in 1 tree, Baltistan District (north), confirmation studies are needed.
