Tomato Leaves Curling

Tomato    Long Island, NY

New homeowner and new to forum.  First attempt at a garden.  Any help would be much appriciated.

One of my tomato plants has stopped growing and the top leaves are curling and feel coarse or dried out.

Could this be due to weather/watering or is this most likely a diseased plant?

Are there any remedies?

Hi Chris,

It's possible that leaf curl could be caused by a virus, but this is usually accompanied by discoloration and more than just the leaf tips. Do you or any neighbors use herbicides? It's most likely herbicide drift and was blown in. If your plants were severely wilted recently, then that would also cause those symptoms. In either case you would not need to do anything and they should recover on their own quite easily. New, healthy growth should begin to appear over the next week or two. If the problem persists, I suggest sending samples of both healthy and diseased leaves to your local plant extension office. Cornell does plant disease ID but I'm not sure if there is anything in NY closer to you. It might also be a good idea to trim off all the affected tissue in case it is diseased, and dispose of it away from the garden or compost.

Thank you for your help. I will keep an eye on it and see if the plant recovers.

I have used Weed-B-Gone. Maybe that is what caused the issue, but would be strange since it is the only plant like that and is surrounded by other healthy plants.

almost 5 years ago.

Hi Chris -
The symptoms are likely the result of using the herbicide. Weed-B-Gon affects both grasses and broadleaf plants. Tomatoes are very sensitive and often develop severely distorted leaves. The herbicide was probably a little more concentrated in this location which is why you are only seeing symptoms on one of the plants. As Matt suggested, it may grow out of it but if the growing point was damaged then it likely won't and should be removed from the garden to give the other plants a little more room to grow.
