Is it Blight?

First off I want to say thanks for the wealth of information here at HG. I've spent the last couple days reading here and I think I have answered my own question from the information posted and also the links some of the members have posted. That link to the Texas A & M site was really helpful.

Here's the dieing plants:

The plants were purchased at a local greenhouse with the exception of 3 that were started from seed. Mulched with straw when they were set, staked with T-posts and supported with nylon hay baling string. Lower leaves cut off when they were real young and I've been fairly diligent with pulling suckers. So the plants have had minimal contact with the soil. I did water with a soaker hose twice after they were set when a dry spell came around. For the last couple of weeks it's been overly wet.

So that's their story and I'm looking for a 2nd or 3rd opinoin on what ails these plants. I am thinking an air born spore got into the plants when they were suckered. Could have been in the soil already, bought the house 2 years ago and don't know the history too well.

Here's a shot some feet away, seems to be enough air flow but the squash is getting kinda big:

Planted 18, 3 dead so far and black trunks on several more. Copper sulfate is what seems to be the recommended treatment from the posts I've seen and a milk solution for preventitive measures (next year).

Any thoughts would be appreciated.

I don't see any signs of blight (early or late). It might be something like bacterial wilt, which will ooze a milky white sap if you cut the stem and put it in a glass of water--or bacterial stem rot.

Milk only works for powdery mildew, which is rare on tomatoes.
