sunscald

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Sunscald is the result of the root system being unable to absorb adequate quantities of water to maintain turgidity in the entire plant. Rapid wilting and death of portions of recently expanded leaves may occur in the plant bed or field during periods of bright sunshine, high temperatures, and low humidity. Sunscald occurs most often after periods of rapid growth and affects the tender succulent leaves exposed to the sun. The affected area turns brown, and shattering of the dead tissue eventually follows. Rapid decline in soil moisture, root pruning by cultivation, poor drainage, or other root disturbances contribute to the severity of sunscald. Stink bugs cause similar symptoms but usually less damage.
