What is this disease?

blynn123August 25, 2013

Our tomato plants are infected with this disease. They have produced a ton of tomatoes but the foliage is dying now. I don't think it is late blight, but I can't figure out what it could be and even more importantly how to prevent it next year!! Any help is greatly appreciated!!! THANKS!!

You're correct. Not late blight.

Please post a picture of the entire plant.
Is it in pot or ground?

Here is a photo of the plant but I just cleared out a bunch of dead leaves. It is hard to see the spots in the photo, but they are there at the top. I can put up a different photo if needed. (Dried up and crispy) It seems to be affecting all of our tomato plants. This one is in the ground, but I noticed it starting on some that are in pots. We used compost tea and sea kelp fertilizer in the beds. Since it is a raised bed we mixed in compost throughout the season. No other fertilizer.

Thanks for your help!

A couple questions: are these plants in pots or raised beds? or both?
How do you water? sprinkler? Hose? Do the leaves get wet often?

Also, what is the nutrient analysis of your kelp fertilizer?

But, you may have Bacterial Speck. You could try a copper-based spray, or a product called Serenade.
