Plum Pox Virus, Potyvirus sp. O PPV, is a grave virus infection that typically associated with fruit bearing plants in the Prunus species such as plums, peaches, apricots, blackthorn, nectarines, cherries, almonds and ornamental plants such as laurels. There are currently 5-6 strains of the PPV virus. The virus is transmitted by sap sucking insects such as aphids*, propagation grafting and substandard inspections of the fruit traveling to other locations. Plum Pox Virus does not affect the actual trees (nor animals or humans), but it will hinder the yield and possibility of market sales.

*Myzus persicae (Green Peach Aphid)

There are several symptoms of PPV (depending on the strain), yellowish to light green blotches or veins, curling, crinkling on the leaves which usually appear during cooler months. The fruit however sustains the most damage. Pigmented spots, rings and discolored flesh and sunken areas on the actual fruit and seeds are common. There is no known treatment or cure for Plum Pox Virus so early detection and removal of the entire infected plant or tree is critical to prevent spreading.
