Gray Mold? Something Else? How do I treat this and save my plants

[tnkrer]

Over my last few years of gardening the axiom that has held true is .. Sooner or Later there is always disease on my big tomatoes. Unfortunately it is sooner this year! And I had made a much better effort at preventing the disease this year. Pruned the plants regularly to keep crowding to a minimum, sprayed copper and Excel LG alternately every week.. and yet, I saw two branches on Neves Azorean Red and one branch on adjacent Sungold wilted/black/dead. All of these were almost at the top of the plant. So I quickly removed all the infected branches, a few infected leaves and sprayed daconil. That was yesterday. I noticed 2-3 infected leaves today. So not sure if I have contained the spread .. Here are some photos.

top of the plant that shows the infection. (Did not remember to take pictures of the worst branches. They were limp and grey with all the leaves dying.)


Stem with black/brown discoloration


Another leaf that was not as infected


So
1. what is this disease?
2. Do I have a chance at recovering the plant? How should I go about treating the plant?

Any help will be greatly appreciated.
