What's wrong with my tomato plants?

[Wildcat]

I found this at the TOP of one of my tomato plants and had to pull it off to be able to get a picture. There are a couple more leaves that look like this on the SAME STREAM and come down about 8 inches from the top.

May be bacterial.

Here is another site that may help you figure it out.

ours has developed a powdery black fungus on the leaves now that we have had a bunch of rain.

Tough year for the garden all the way around.

Tough year indeed, go from no rain to too much.

Well the too much rain to no rain doesn't effect me and the Earthboxes. The plants will ALWAYS get all the water they want as long as I keep the reservoir filled the plants will take what they need.

The only plants that are giving me problems are the Brandywine tomato plants, the Big Daddy's are fine.

Its a fungus and you have to destroy the entire plant if cutting off the infected stems doesn't clear it up. Overhead watering spreads it like mad. Pick up all the leaves on the ground, the infested branches, bag em separate and seal it tight. There are sprays but I can't read the label and then eat the fruit, just can't do it.
