Senescent spots on an over-ripe banana (Musa sp.) fruit.

Definition

Senescent spots are small necrotic areas on a fruit's skin that can form naturally as ripening occurs.

Discussion

When bananas reach ripening category 7, senscent spots form naturally and are not a sign of infection or disease. The development of spots can be controlled by farmers and ripeners by on-time harvest and by adjusting the parameters of ripening.
