Default Problem with Damson Tree

Peter
With the caviat of not having seen the problem.
I am not familliar with mealy plum aphid.
Having checked Stefan Buczacki's Pest, Diseases & Disorders of garden
plants - he does list it. He states that the leaves are not deformed
by this pest, they exude a lot of honeydew resulting in sooty moulds
(as leaf curl aphid does later in the season) and that it does not
build up to damaging levels until mid summer.
If the leaves are curled then I would suggest it is plum leaf curl
aphid.
