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.
The use of certain herbicides can lead to leaf curling, though this is not considered true grape leafroll disease. Nutrient deficiencies can also cause grapevine leaves to curl. If the soil where the grapevines are planted is deficient in potassium and phosphorus, the leaves might begin to curl.
