Spraying potatoes with Dithane

[rodofgod76]

I've got about 30-40 potato plants in the garden in massive planters. Most are Arran Pilot's and there's maybe 15 or so Edzell Blue's. Just wondering if I should be spraying them with Dithane or if it's too late? Lost all of our Carlingford's last year to blight and don't want a repeat this year. They were all planted around easter time this year.....so when should I be looking at getting some spuds?? And do I wait until the tops die off? They're just starting to flower now.

so many questions!!!

a - check blightwatch to see if there is a report of a full smith period - if so then spray once a week.

b - have a furtle and see, we've been eating furtled Kestrel for weeks now

c - yes, wait until they die off but pick the flowers off as you want the energy to go to the roots not the flowers and the fruit that will follow.
