Pepper, Eggplant : Physiological leaf roll
(revision date: 6/3/2014)


Biology
Physiological leaf roll of pepper and eggplant is a cultural problem associated with drought, high soil moisture, or high temperatures. The leaves of the plants roll downward and become leathery or brittle in texture. Symptoms may resemble those caused by virus diseases, but plants remain green and are not stunted or deformed. Growth is not usually affected. This is a common problem that causes no damage to the plants and does not seem to affect yield.
