For those who have been seeking information on the relative resistance to blight in potato varieties the Potato Marketing Board has an excellent database which provides this information as well as the relative resistance to other diseases ...

Thanks, that seems to be just what I need.
Does it take accouint of the new strains of blight?
Looks like T+M are making money out of me next year.... I had to burn half my outdoor tomatos today and I fear there are spots on some of my others and some potatos. Wiull cull all affected foliage and get busy with the Dithane on whats left (sprayed Bordeaux mix today)

amphibian - I doubt that it does in part because there is probably a lack of adequate data at this stage. The only variety that I have heard of is Lady Balfour which has a high resistance rating in the database but is not living up to this billing when A2-Blue13 is present.
As a cynic I do not believe in total resistance and so I simply use the numbers to see how one variety stacks up against another, eg Romano (son of Desiree) has greater resistance to blight on foliage than Desiree itself .. and I will continue to use this approach until such time as somebody announces that (say) Romano is susceptible to A2-Blue13 .. not a lot else one can do.
Do not click the above link :-X :-X :-X :-X
.... or any other by that poster in other threads.
Why?
Because they are obscene and offensive and Dan has just removed the poster.

That makes perfect sense.
