I noticed a few leaves with L Blight in some rows of my potatoes a few days ago this was followed by 2 consecutive Smith Periods :'(
I've cleared most of the foliage in surrounding rows, but I've left those that are meant to be resistant types :-\ not sure if they may harbour spores?
I have a another couple of patches of potatoes fairly close and as yet no sign, although I not very hopfull. Many of these are varieties grown from TPS. I hope some will have either produced berries or small tubers which I can grow next year. Though some are only just starting to flower so not looking too good for them. I'll keep a close eye and first sign they will have to go.
For a measure of blight resistance I'm growing Sarpo Mira and I'm trying these varieties alongside Sarpo Kifli, Toluca and Tuskar. Also several of Tom W TPS varieties I'm growing, including Skagit Magic are reported to have resistance to L Blight but we have different strains over here, so...
I'm hopeful some will make it and also some berries from crosses of resistant potato.
No sign on my tomatoes yet.
I've sprayed my outdoor tomatoes with Serenade, an organic fungicide. first time I've used it and perhaps a bit too late.
