Description:
One symptom of sunburn on fruit is large, white spots, particularly on the southern side of the plant.
Most of the Solanaceae family -- tomatoes, peppers and eggplants -- are especially susceptible.
Control:
The only sure way to prevent sunburn on plants is to grow a strong plant with good leaf coverage.
Give it the proper nutrition to help make sure the foliage provides ample cover for the fruits.
Leaves have an even more important function. The plant's food for growth is manufactured in the leaf area.
There's a critical point at which the plant goes into a reproductive mode instead of a
vegetative mode of growth.
But if it hasn't made enough vegetative growth, it won't bear
fruit as it should.
