It's fungal spores affecting the potato and tomato family which spreads in May/June during periods of warm, humid weather.Once the weather cools down it lies dormant in debris in the soil which is why you need to rotate.
I understand it becomes windbourn in Spring and falls onto the leaves of those plants which is why the first signs are the browning of the leaves. Later it travels down the plant, eventually affecting the spuds ( and tomatoes).

Have a look at this site...

Apperantly where our allotment is sited Blight has been there for many, many years. The majourity have given up on Toms and Spuds, it tends to be only the new commers who try- generally only the once!. We found out the hard way last year, gutting to see a whole GH of Toms burn.
One plot owner (who shall stay anon just in case!!!) has imported a substance which is banned in the UK, and is planning on using it and is trying to get all the other plot holders to do so also, a bit worrying.
I don't think for a minute they will as allotments are 99% organic/biodynamic.
