Try www.GardensAlive.com because they have something called Pyola. I
like it for all sorts of pests in my container garden (I don't get
very many beneficial bugs here). But remember, it will kill
beneficials as well. What you need to do is buy some ladybugs and
lacewings and let them loose in your tree. They will take care of the
aphids for ya.

My plum tree is infested with aphids I sprayed it really good with a soap
insecticide but did not help.
I far as I can tell it's aphids (small green bugs). The tree has lots of
sticky leaves and some webs on the leaves.
What else can I try?
