Pests

Tomato plants are susceptible to various pests that can cause the leaves to curl. Some of these pests include aphids, spider mites, and whiteflies.

Curly leaves can also be a symptom of various diseases that affect tomato plants. One such disease is tomato mosaic virus which causes the leaves to curl and twist. Other diseases that can cause curly leaves include peach potato aphid-borne yellows, tomato yellow leaf curl virus, and tomato bushy stunt virus.
