Symptoms vary depending on the crop and are mainly characterized by a blossom blight and a fruit rot phase. The first symptom of blossom blight is the withering of flowers, which turn brown and often remain affixed to the twig in a gummy mass. Infections may extend into the twig and can girdle it. If shoots do not die off completely, the infection is carried over from the blossom to the developing leaves and fruits. Leaves dry out but remain on the tree throughout the whole year. Fruit rot can affect fruits hanging on trees as well as stored ones. Soft, brown patches appear on the fruits. As the patches grow, white or yellow pustules develop on the tan areas, sometimes in concentric circles. The fruits gradually dehydrate, rot, and mummify on the tree. Stored fruits may not develop pustules and may turn completely black.
