I just use hormone rooting powder....fresh every year. I used to use Cheshunt compound but no longer available.
keeping pots clean, using fresh compost, not over doing the number of cuttings, not over watering is as good as any fungicide I think.
I'm sure any ordinary fungicide can be used on cuttings and soil initially can be used. i don't bother though
