How to Manage Pests

Pests in Gardens and Landscapes

Physiological leaf roll in vegetables

In peppers and eggplant, symptoms of leaf roll include the downward rolling of leaves, generally on all plants, with no yellowing of new leaves and no stunting.

On tomatoes, firm and leathery leaves are common symptoms; the lowest leaves roll upward in wet spring conditions. The tomato plant may look wilted.


Physiological leaf roll is very common. This is not caused by a pathogen. No action is needed. It will not harm plants.
Tomato leaf roll symptoms disappear when temperatures become warmer and soils dry out. Normal growth resumes and there is no damage to the fruit that develop later.
