Tomato: Physiological leaf roll

Biology

Physiological leaf roll of tomato is a cultural problem which may be associated with high soil moisture, high temperature, drought, or heavy pruning. Plants with a heavy fruit load are often more severely affected. The leaves of the plants roll upward and become leathery. Symptoms may resemble those caused by virus diseases, but plants remain green and are not stunted or deformed. Growth is not usually affected. This problem causes no apparent damage to the plants and does not reduce yield. Varieties differ greatly in their susceptibility to this problem.
