Symptoms of PPV are variable depending on the strain of virus, the host species, the host cultivar, and may take several years to develop. Leaf symptoms include pale green spots, rings and lines, and sometimes leaf twisting or distortion. Usually only some of the leaves on a tree are affected. Fruit symptoms include rings, lines and blotches, as well as sunken lesions. The pit may also be marked with rings or spots.
Affected fruit have poor flavour due to low sugar content.
