The tomatoes on the allotment were just starting to ripen.
Then the heavens opened for a week.
Now there is significant brown rot on some plants and a lot of unripe fruit.
Although we have taken a load of ripe fruit off the tomatoes it looks
as though the crop may well be destroyed very soon.
I assume this is worse on allotments than at home because the tomatoes
at home are still fine.
Is it possible to save some tomatoes by removing most leaves and all
infected parts of the plant?
Yes, then spray the plants with a solution of Epsom salts every day for
a week.

I had blight in my tomatoes last year and followed this advice. It
checked the spread of the blight without completely stopping it. This
year I grew most of mine from seed and have had no trouble - so far.
