Sunscald
Sunscald: Tomato fruits nearing maturity when exposed to the sun are prone to scald. The tissue has blistered water-soaked appearance. Rapid desiccation leads to sunken area which usually has white or grey colour in green fruit or yellowish in red fruits. Any factor causing a loss of leaves, such as disease, will expose fruits to sunlight and increase chances for sunscald.
Control: Maintaining a continuous disease control program will lessen chances of foliage loss. Covering exposed fruits with straw, if plants are not staked reduce the incidence of sunscald.
