Potato protection

I was wondering ... those of you who spray potatoes against blight, what is your plan now that Dithane 945 is no longer to be available for domestic use ? Bayer seem to be offering a copper fungicide as an alternative.
Personally I don't spray anything, and I do compost the haulms if they are healthy. Perhaps I'm lucky or perhaps its the lower rainfall out east, but I've only once had blight on potatoes, and in that event I burned the tops and any affected tubers. Easier said than done with something which is 90% water ! I had to do it under cover of darkness to avoid complaints ...
