If your tomato plants are producing tomatoes but the edges of the leaves curl upward, this is known as leaf curl or leaf roll. If your plants are not producing, and the leaves are yellowing as well as curling, it may be due to a viral infection.
Fungal Infections. Fungal infections are the most likely culprits if your tomato plants have lower leaves that are beginning to wilt and die. The fungus typically flourishes in the moist heat of summer, just as the tomato plants are starting to fruit. Possible fungal infections include Fusarium wilt, early blight, late blight or Septoria leaf spot. Although these each present with different symptoms, all tend to affect the lower leaves first.
