Apricot Scab

Prunus armeniaca L.

A fungal disease of apricot caused by the pathogen Cladosporium carpophilum, affecting fruits, shoots, and leaves. It is characterized by the appearance of dark, velvety spots leading to fruit cracking and deformation of current-year growth.

In the reference 7 varieties crop Apricot, where this is mentioned in the description.

The causal agent of apricot scab is the mitosporic fungus Cladosporium carpophilum Thuem. The first signs of fruit infection are observed in the first ten days of June as small greenish-brown spots, which darken over time, acquiring an olive or black velvety coating. In cases of severe disease development, the spots merge into a crust, the fruits stop growing, crack, and drop prematurely.

On current-year shoots, the disease manifests as numerous small brown ulcers that inhibit growth. Leaves are affected less frequently, mainly towards the end of the growing season, with diffuse pale green or brown spots forming on their undersides. Genetic markers or specific races of the pathogen for this crop have not yet been described, and breeding is conducted primarily based on the evaluation of field resistance of cultivars.
