Plum pox Plum pox Plum pox, also known as sharka, is the most devastating viral disease of stone fruit from the genus "Prunus". The disease is caused by the plum pox virus (PPV), and the different strains may infect a variety of stone fruit species including peaches, apricots, plums, nectarine, almonds, and sweet and tart cherries.
