What Bob says about removing the tops is of course correct and that stops
the blight getting to the tubers. Preferably you want to dig the remaining
tubers on a hot dry day, yes well !!

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.
