Scab first appears as velvety, dark olive-to-black spots on fruit, leaves, and stems. The olive velvety spots are the sporulating fungus and growth of the pathogen on the lesions. When infections occur early, fruit spots become scablike with age and the fruit may become misshapen. On leaves, infections cause leaf puckering and twisting and eventually tearing with age. Secondary infections that occur later in the season appear as black pinpoint spots on fruit and leaves.
