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.
Herbicide damage, particularly from 2,4-D, may cause tomato leaves to curl first downwards and then upwards. In this case, the plant may show such effects as cat-faced fruit, stunted growth and twisted leaves. If the exposure is mild or minimal, such effects aren't seen, and any damage will be outgrown.
