My wife uses 1 teaspoon of liquid dish soap to a liter of water and hand
sprays her indoor plants every couple of weeks to control aphids. Maybe you
could make this method work for you. You need to get both sides of the
leaves. The other method is with the use of lady bugs. Their best Sunday
meal consists of aphid eggs.

I read that growth after May shouldn't be affected, but i'm wondering
if anyone's had any success controlling this disease? Should i hard
prune the affected shoots to healthy leaves lower down after May in
hope of tree responding in healthier growth.

The important thing to remember about the leaf-curl aphid is its life
cycle. It appears on the leaves of prunus trees, but that is at the end
of the life cycle. The aphid's eggs drop to the ground under the tree,
to overwinter, then the larvae hatch, the adult emerges and climbs up
the tree to infect the leaves.

If you prune affected shoots, make sure to burn them. After that, have a
thorough clean up all round the base of the tree and do that again in
autumn time. Grease bands round the trunk can help, but they are not
100% effective.
