Sunscald occurs when fruits are exposed to high temperatures and intense sunlight, particularly when once shaded fruit are suddenly exposed to intense sunlight.
The exposed fruits start small patch of discolored section. The fruit tissue will become soft and wrinkled. Affected fruits will form sunken dead areas on sides exposed to the sun.
Eventually the tissue turns tannish white and papery in texture. Saprophytic fungi and bacteria may attack damaged tissues and those tissues will become discolored and rotten.
