another pic.

And another

And the last one.

Your leaves look identical to mine. After spending hours studying pictures I think it is safe to say we both have Tomato Septoria Leaf Spot. The website below has great pictures. What cinches it for me is the description of the circles. Our circles are pretty tiny and with early blight it seems they would be bigger. I am new to gardening so I will have to learn how to take care of this. Really bummed :(.

Looks like there is no way to treat this without chemicals. I am completely out of luck as I am in an organic community garden, near water and am allowed only a short list of acceptable organic products none of which treat this problem. What is weird is that my tomato plants look great and robust. Just a few bottom branches have this.

Looks like there are some organic controls -- some suggestions here on the site linked below. You can cut off and destroy the bottom branches and sounds like all will be okay -- I hope so.

Here is a link that might be useful: from missouri botanical garden -- septoria leaf spot of tomato

Oh Elisa I hope so too :(. Never had a fungus problem before. FIrst time in a community garden so I am learning a lot. I will check those links out. Thanks so much!

Oops, double post. Edited it out :).

garden gal and lanidel - I have two sprays that should help with this and they are both organic, OMRI listed. One is Copper soap fungicide, and the other is Serenade Garden, (Septoria is one of the things it says it works on )

You cut off the affected leaves first, then spray the healthy ones to prevent the spread.

I wish you both good tomatoes!

Also, there is an excellent thread on the Growing Tomatoes forum about organic controls for Septoria.

Your plants have Bacterial Speck IMO but the treatment for all the leaf diseases is the same - strip off affected foliage ASAP, cease any overhead watering/sprinkling, and spray with fungicides on a regular basis to slow the progression of the disease till you can get a harvest. There is no "cure".

And yes there are a number of ORMI approved fungicides available although their benefits are questionable when compared to chemical controls.

As already mentioned you can learn much more about all this over on the forum for growing tomatoes here.

Thanks for the tips! I will head over there. Now I am not sure which one I have. I swore I had septoria leaf but don't have a pic to post. Removed and disposed of all affected leaves and I am going to start spraying the only acceptable fungicide by my picky community and hope for the best :).
