Shothole of Stone Fruit

Stigmina carpophila


A fungal disease that initially causes small brown spots with reddish rims on leaves. These spots grow and the centre falls out leaving a round shot hole in the leaf. Irregularly shaped holes may be formed where spots overlap.

Round or oval spots that are raised or have raised edges and exude gum may appear on twigs and stems. Twigs may die from girdling.

On Apricot fruit round, brown scabs with exuding gum are produced.

On Almond fruit copious amounts of gum are exuded and the fruit may crack.

On Peach and Nectarine fruit the spots may develop into deep indentations.
