Can tomato plants recover from herbicide damage?

Herbicide injury can’t be reversed, but if the symptoms are not severe and the plant does not die, new growth may be normal. However, the likelihood of a plant fully recovering from herbicide damage is low. Plants injured by herbicides often produce fewer flowers and are stunted, resulting in reduced yield.

What does herbicide damage to tomatoes look like?

Tomatoes are very sensitive to 2,4-D (see above photo), with injury from herbicide drift usually occurring in May and June. Leaves become twisted, curled, and strappy and stay small in size. Injury is observed on the youngest leaves. Plants rarely outgrow the injury caused by this growth regulator.
