Woolly Aphid damage on apple tree

[JohnD]

I am used to aphids, and generally spray the garden. I have a smallish apple tree that I have not sprayed for several years, and it was heavily infested with woolly aphid. Many shoots had died and some branches, and the trunk bark was split, and it has some large galls..

I have cut away all the damaged timber, treated with aphid spray and painted the wounds with a waxy water-repellent stain. I inspected it 10 days after treatment, amd found a few remaining patches of wool which I treated with insecticide.

I was surprised to find that woolly aphid attacks the surface of the wood, not the leaves. Is there any persistent or systemic treatment that will prevent them recolonising the tree?

Don't know much about creepy crawlies John, but I'm pretty sure you shouldn't splashing Cuprinol onto a tree, especially one you eat fruit from.

not cuprinol

fernce stain is just a waxy emulsion in water with a bit of colouring

That tree has died now

but I have a small infestation on another apple tree at the other side of the garden.

Any recommended traetments?
