Blight in the house?

I queried the local extension office again about my tomato problem, and here was their response:

I’m sorry I don’t know what other tomato questions you may have had or what information you may have received, but I am including a link to a general information sheet about tomatoes.  It appears that you may have a fungal disease on your tomato plant.  The best defense against tomato fungus is choosing a disease resistant variety however most heirloom tomatoes are susceptible.  Page 4 of this handout at the above link lists fungicides that can control fungi on tomatoes.

Good luck and I hope this is helpful!

Is this early blight, perhaps?  I dunno but it doesn’t sound good.

I went ahead and picked up some organic fungicide, by GardenSafe, which is basically neem oil (it’s all they had at Home Depot).  When I got home I clipped off all the affected leaves/branches, sprayed the other leaves down with the fungicide, and scattered some corn meal on the soil per this link and various other forum postings.

I was also curious about some white, mildew-looking stuff on top of the soil in the new cucumber plant, so I went ahead and sprayed that as well.
