Here in the Pacific Northwest, we have late blight, too. I've mostly had good luck by avoiding overhead watering and mulching heavily. But I read about an old time anti-fungal remedy that I might try this year, if things get really out of hand: 1 tblsp. baking soda, 2 1/2 tblsp. vegetable oil, 1 tsp. of liquid, organic soap (not detergent) to a gallon of water. The directions said that it is completely non-toxic but can burn leaves, so it's best to try spraying it on just a few leaves and wait a day or two first to see how it is tolerated. If it's a "go," spray all parts of the plant every couple of weeks.

We garden in the central Idaho mountains, with a short season & a freezing winter. I have never seen tomato blight in my gardens & I wonder if this is a tomato advantage with freezing winters? ca, your anti-fungal remedy sounds like my very effective spray that *disappears* powdery mildew. I've never put baking soda in my spray - the oil *interrupts* the connection between a parasitic fungus & the host plant. I found it worked perfectly on hard-surfaced leaves such as Aster Laevis or Current or Gooseberry bushes. It was not as well tolerated by Basil, which seems more tender to me than Tomatoes. Your advice to try is little first is good ...
