Bitter Pit

Symptoms

Circular or slightly irregular depressed spots appear on fruit surface, beneath which are brownish or streaked necrotic areas. Pitting (discrete necrotic spots) may not always be visible from the outside of the fruit. Necrotic tissue is usually soft until it dries out. Pits are more numerous on blossom end of the fruit. These may appear on the tree or in storage after harvest. May be confused with stink bug feeding damage, which is a depressed blemish with a puncture site is always visible in the center leading to a brown cork-like area in the flesh.
