Can anyone tell me what is on my tomato plant and if it can get on another one that I have. It started out like black spots around the edge of the leaves and then turned yellow, curled up dry. The new growth does not have it.

I agree with everyone else about the fungus. This is a blight and it’s unfortunately on your plant. I would prune off affected leaves, buy some Neem oil and spray the remaining leaves. Neem oil is an organic antifungal from the Neem plant. If this doesn’t work, you may have to use some copper fungicide. I may suggest to use that sparingly. Good luck￼👍

Good morning, it’s a case of early blight on your tomato plant it’s a fungal disease that is bought on when it starts warming up and it’s also involves the humidity of being humid. Look up on Early blight fungal disease.

You can remove the affected leaves and spray it with a fungicide.

Sounds like a nutrient deficiency, do you use plant food? Tell me if this sounds right or if you agree. This may not be exactly but probably.

My tomatoes always get blight where I live in southwest Ohio, but I found a variety (Beefmaster) that gets it very late and so the plants don’t die until I’ve gotten a good tomato harvest. Fortunately they don’t get early blight. You might try that variety or ask others where you live what works best for them.
