You can try Dithane 945 but imo it's a waste of time trying to hold off
the blight as once it's in the vicinity, it doesn't seem to be stopped
very easily.
Everyone on the allotments suffered blight this year, but the local farmers'
crop is down by 20% and they spray. I may give Dithane a try next year -
assuming seed pots are available!!
