Hi John
Tomato blight was not an unusual event last year. I have had blight
on my outdoor tomatoes (but not potatoes) for the last 7 years.
One year I tried Bordeaux mixture on them (before the blight) and it
delayed it a bit but left a nasty bluish-white powdery deposit on the
leaves and fruit, which made them nasty to handle and every fruit had
to be washed before eating and I didn't like it on my hands. The
blight still arrived!
I grow them on my allotment and everyone suffers the same.
Blight usually comes in August, or after a dry period when the rain
comes, and the rain brings the blight.
I have heard that if you can make a polythene shelter over the outdoor
plants to keep the rain off, you may keep the blight off too.
That site looks useful. I got info from HDRA (now called Garden
Organic).
Good luck
