Peach mosaic virus

PLMVd is principally a disease of peaches. Symptoms vary depending on the virus strain and the peach cultivar, but most infections lack obvious symptoms. Symptoms such as flower streaking, wood grooving, and leaf mosaics tend to be sporadic.

In parts of Europe, a strain of the viroid causes peach calico, which has more severe symptoms such as fruit blotches and a leaf mosaic that causes white patches over large areas of the fruit and leaves.

While infection by PLMVd alone typically does not cause noticeable or undesirable symptoms, PLMVd-infected trees are more susceptible to both biotic and abiotic living and nonliving stresses. The combined effect of a co-occurring infection or stress can increase symptoms and lead to economic losses. Grafting, pruning, aphids, and pollination can transmit this viroid, but grafting is the most efficient means of transmission. Delayed bloom is a desirable trait in peach-growing regions prone to late spring frosts and grafting with PLMVd-infected source plant materials has been used both intentionally and unintentionally to impart this characteristic to trees.
