Included in this genus are multiple species of trees and shrubs, such as: Dibotryon morbosum infects are Prunus serotina (wild cherry trees), Prunus persica (peach trees), Prunus domestica (plum trees), and Prunus cerasus (sour cherry trees). [3] The main symptom of Dibotryon morbosum is its “knot-like” gall structure. These knots can vary ...
In Verticillium, the symptoms and effects will often only be on the lower or outer parts of plants or will be localized to only a few branches of a tree. In older plants, the infection can cause death, but often, especially with trees, the plant will be able to recover, or at least continue living with the infection.
Almond, apricot, nectarine, peach, plum and cherry trees can be affected. Both edible and ornamental varieties are vulnerable to infection. [ 2 ] Almost all over-ground parts of the plants are affected including the fruits, buds and the stems, but the damage is most noticeable on the leaves.
Possible symptoms produced tend to vary from white gray mottling on field maple to yellow chlorotic spots on hawthorn leaves. [1] There is an Apple Necrotic Mosaic Virus (ApNMV) which is a very similar virus but displays signs of necrosis. [6] Furthermore, in plum trees, ApMV can cause line-pattern symptoms, while in roses, the symptoms are ...
