Diseases
Prunus armeniaca L.
Tissue necrosis in apricots is not an independent disease, but a symptom of infectious lesions caused primarily by verticillium wilt and bacterial pathogens.
In the reference 3 varieties crop Apricot, where this is mentioned in the description.
In the case of verticillium wilt, caused by the fungi Verticillium albo-atrum or Verticillium dahliae, necrosis affects the tree's vascular system. On a cross-section of the branches, the damage appears as a dark ring in the wood, which leads to the blockage of vessels and the rapid death of individual parts of the plant.
Bacterial necrosis, caused by pathogens such as Pseudomonas syringae, affects all structures of the apricot. Externally, it manifests as formations on the bark resembling sunburns, which eventually turn into deep ulcers with gummosis and patches of dead, 'charred' tissue on the branches.
