Hi All,
This tree about 30 years in garden never had a problem. During the year I sprayed it with a 50/50 skimmed milk and water mix thinking it might get rid of greenfly. A couple of weeks later the leaves began to wither. The leaves on my neighbours side which were not sprayed are unaffected. Any comments advice help would be appreciated.

Never heard of a watery milk solution to aphids.
I used to use diluted washing up liquid.
Maybe some bug has been attracted to the milk residue. Spray it with the washing up liquid mix and wait for regrowth? Can you see anything on the underneath of the leaves?

Chances are it got a bad dose of powdery Mildew. Acer's are very prone to this in the summer particularly if the air has been still and dry for a while. Shouldn't cause any great harm apart from aesthetics.
Your neighbours side might be the more windward side which may have prevented P mildew building up there.
The milk mix should have dripped off rapidly without causing damage. Won't kill aphids though.
For this use SB Plant Invigorator, natural safe product.

No problem hitbit, SB for aphids and a fungicide containing myclobutanil (found in most rose sprays) for P Mildew. Get it early in the season and you shouldn't have a problem.
