I can only quote what I have found.
Apple scab has been a major problem on an old Macintosh which was in the garden before me. Every year I've tried to eliminate with various chemicals and it always comes back.
This year I've used ACT on it and there was no sign on any of the fruit we picked. I won't be certain till next year, but I believe I have fixed it.
It would seem that if you can use ACT early in the cycle it will help to eliminate a variety of problems, but once the disease is well established not so much.
