Sunscald on Beans

Sunscald symptoms first appear as small water-soaked spots on upper surfaces of leaves, stems, or pods that are exposed to the sun. These spots are generally close together, turn reddish brown, and form large spots on affected plant parts.

Solutions

This condition is caused by exposure to intense sunlight and/or high temperatures. The problem tends to be most severe following periods of high humidity and overcast skies. No control is available.
