I would definitely look at making up a dip consisting of Biota Max, MycoGrow Soluable and Actinovate to dip your seedlings in prior to planting them in the ground. Ami

PS: The verticillium pictures from Cornell:
http://vegetablemdonline.ppath.corne...Vertic_Tom.htm

You can see to the right side on the bottom picture that leaf right in front
that has necrosis on the tip of the leaf. That is characteristic of
verticillium. I have it in places in my garden, and plants that are
susceptible to verticillium wilt always get leaves that look like that
as the initial symptom.

As for the "dead leaves 3/4 of the way up the plant" that your pictures
show, lots of tomato diseases look like that after the infection has
progressed aways, including verticillium and fusarium. But I do not
see the "partially infected leaves starting from tip back" of verticillium
on your plants. I also do not see the stem lesions of fusarium.

It would have been good to cut some stems during the season and
look at the inside on those infected plants.

I did check the stems on some during the season, no signs of verticulum. Nothing else I saw compares to any of the pics that I can find of Verticulum. I know these end of season pics are useless. Next season I will start taking pics early, hopefully that will help discover what exactly it is.

I wouldn't be too concerned about an exact comparison of what you have seen in your garden and what you see in pictures of common tomato diseases on the Internet. Even pictures of the same disease can have a somewhat different appearance. Even the description of the disease seems to vary. Maybe it has something to do with the area of the continent where the picture was taken and the symptoms that are observed in that area.
After saving the high resolution version of your pictures to my computer and zooming in a bit, I can see the spotting that is typical of Septoria and although there is not enough detail of the leaves to be sure, I would bet you have Early Blight too. Both are the most common afflictions of Tomato plants in the North. I don't see any mysterious disease at all, I see what I have seen in my own garden at times with Septoria and Early Blight.
I also see on the leaves of the squash plants you had growing among the tomatoes what appears to be powdery mildew or downy mildew, unless you were spraying with something that left a white film on the leaves?
