Story: Apples and pears

Black spot

Black spot

Black spot or black scab (Venturia inaequalis) is a fungal disease of apples, and spreads quickly in warm wet weather. It usually first appears in spring on young leaves, as small spots about 3 millimetres across. If young fruit are infected they may become misshapen or develop deep cracks. Granny Smith apples are quite susceptible to the disease.
