I am pretty sure that in my garden I have a case of powdery apple mildew.
Can anyone recommend a systemic spray (which is still available !!!) that I
could use and/or any other management tips?

I appreciate that there are sulphur based preventative treatments but I
really want to attack it systemically as it seems to be a heavy and damaging
attack.
