The fungal spores over winter on fallen leaves or in severe infestations in twig lesions. Wet or dull weather around blossom time will encourage the spread of this disease. The fungal fruiting bodies are produced in spring and infect young leaves which develop white spots and then become blackened, then grey and some leaf blistering may occur. The spores are blown or splashed onto the leaves and fruit. Dark spots appear on the fruit and turn into a blackish brown corky area which may nearly cover the whole fruit. | |
