Dibotryon morbosum is a fungus that affects the genus Prunus. 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).

Peach leaf curl is a plant disease characterized by distortion and coloration of leaves and is caused by the fungus Taphrina deformans, [1] which infects peach, nectarine, and almond trees. T. deformans is found in the United States , Europe , Asia , Africa , Australia , and New Zealand . [ 2 ]
Historically, the disease is believed to have originated in Austria, but is now a minor presence for all peach trees typically east of the Rocky Mountains. As a minor disease, peach scab is most dangerous when the scabs develop—allowing brown rot to infect the plant, which is a far more devastating disease. [11]
Myzus persicae, known as the green peach aphid, greenfly, or the peach-potato aphid, [2] is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues.
Venturia carpophila is a species of fungus in the family Venturiaceae. A plant pathogen, it causes freckle, black spot, peach scab or black scab of peach. It has a cosmopolitan distribution. The species was described as new to science in 1961 by the Australian mycologist Eileen E. Fisher. [1]
Trametes pubescens is an annual, saprobic fungus, a decomposer of the deadwood of hardwoods, growing in clusters on logs, stumps and downed branches. (It is rarely reported on conifer wood.) It is a purported plant pathogen, infecting peach and nectarine trees. [1] It is inedible. [2]
