You can spray with dithane or apply Bordeaux mixture as a preventative
measure but I have never found it to be successful. I have stopped growing
outdoor tomatoes and am growing Thompson and Morgan blight resistant potato
varieties and hoping that they stand up to this summer's weather, which must
be the ultimate test.

We have a big problem in France with potatoes, Colorado Beetle, all
the potatoes have to be sprayed, it is a great problem in the area
where our house is.
