Plum_Pox

Plum Pox Plum Pox Virus (PPV) has not been in the United States until its introduction to peach trees in Adams County, Pennsylvania, 1999. The origin in which the disease has come from is unknown to the Pennsylvania orchard, but it was been in other countries such as France, Egypt, and Chile. The very first plum pox was found in Bulgaria in 1915 and has spread to the other countries aforementioned (Plum Pox). There are many different strands of PPV that are capable of infecting plums, peaches, apricots, nectarines, sweet and sour cherries and almonds. Healthy plants of more than twenty different ahid plants are at risk, due to the spread of the virus through budwood and grafting (Plum Pox Virus). PPV Strains There are four different types of strains: PPV-D; PPV-C; PPV-EA; and PPV-M. PPV-D (Dideron) is the most common strain of the virus and was originally isolated from apricots in southeast France (Levy). This strain is not known to be seed-transmitted and is the non-epidemic form of the virus. PPV-M (Marcus) is more aggressive in peaches and the aphids are more effective in spreading the virus in an orchard than the PPV-D strain (Plum Pox).
