here is a second picture

Curling of those top leaves very suspicious of herbicide damage Either volatilized from nearby or in contaminated organic matter, such as manure used in the beds.

I noticed yellow spots on the leaves of my tomato, green pepper, egg plants and sweet potatoes. My neighbor tree has branches extended into my backyard and leaves from the tree falling on my plants. He does not spray or do any thing to that dam tree. I think the tree is infected and infecting my plants. I sprayed my plants with CAPTAN. I am thinking to spray the tree branches in my backyard too. any thoughts

foolishpleasure, your question isn't related to this thread; it would be better to start a new thread (which you can do at "Post a Message to the Forum" near the bottom of the Tomato forum main page).

There are many different causes for spots on tomato leaves. Unless you post photos, we can only guess what the problem is.

Tomatoes, peppers, and eggplants are all related and share some diseases. Sweet potatoes aren't related to the others, and probably don't share many diseases (mildew, I suppose).

What kind of tree is it? That's important to know. If it's a black walnut or butternut, the leaves could be a problem for your plants because of juglone toxicity -- and if the leaves are above your plants, there would probably also be roots under your plants which could also make them sick. But that would only be if it's a black walnut or butternut or perhaps some other related trees (sometimes it depends which rootstock was used for a grafted tree).

You can post photos of the tree (particularly a good close-up of its leaves) on the Name That Plant forum, and they'll identify it for you.

I'm thinking that herbicide inside a greenhouse is not very likely. But you never know.

I have leaf curl but it is only on Burpee Supersteak plants. Even called the extension office about it. Do beefsteak types tend to do this more? I have two different garden beds a half mile apart. Different manure in each bed. Supersteaks look the same with leaf curl. Extension agent actually saw one of the plants. He suggested watering. We'd gone 3 weeks without rainy and I had been watering, hopefully not too often. I think it helped some, but I still have leaf curl on the Supersteaks.

Cory, based on just your second picture b/c you have some other stuff growing in that greenhouse, if it were me I'd ignore it for now.

It's either physiological Leaf Roll, in which case when root and foliage mass are in more balance it will go away, or it's just plain leaf Curl in which case that can happen when it's too dry, too wet, too hot, too cool, and in such smaller plants such as yours that too might go away as they mature.

If the leaves curl over into a tube structure check for aphids. Aphids love greenhouses.

From that one picture I don't see any evidence of herbicide damage.

Since you say that all of your indet plants are showing it, then I assume that it's more environmental and/or a function of the plants going more towards maturity than anything else.

If any other symptoms show up please let us know.

You haven't used manure, compost or hay that coud be contaminated with clopyralid or picloram?
