Late blight in Maryland

Thanks to Kathy from Skippy's Vegetable Garden blog for making me think about late blight.  She mentioned that blight has been seen a few hundred miles from her gardens which made me wonder about proximity to my Columbia plot.

It was identified in Montgomery County on June 20, 2013.  Oh.  Boy.  http://www.usablight.org/  I've also added this link to the blog's sidebar for future use.

Having never dealt with it before, I've had to do a good bit of crash reading.  I do have some signs of some fungus distress in one of my boxes (the volunteer tomato in the flower box), but I'm not certain that it's actually blight.  More reading will be necessary.

From what I've read in a couple locations, using Actinovate spray and along with spraying a Copper Fungicide is recommended.
