In the same book that I was reading that gave BER info updated, I also discovered that it is best for blight resistance on those varieties that usually go down with it all too easy, - to let those tomatoes grow as if in their wild state with absolutlly no pruning or trimming and very little staking-so that they grow bushy and sprawling-and apparently this extra leaf and branch sheilding stops most of the blight-save for a few outside leaves, and you get a much more likely crop from them-rather than nothing.
But only for those varieties that easily go down with it, all other varieties can be treated as normal.
