Post category: Brown rot
Brown rot is a fungus disease of plums and occasionally cherries, apples and pears. It causes a brown rot, often with white spots, which destroys the affected fruit. It is rarely a very serious problem, destroying only a few fruits usually. It can also cause ‘shot-hole’ of the leaves, tiny round pieces dropping out to leave a hole.

Pick off all old ‘mummified’ fruits left on the trees in the autumn. These are the main sources of infection. The sprays for apple scab help in prevention.
