plum problem

[JohnVisual]

Hello. Can anyone please tell me what is attacking my plums. They leak sap then shrivel up and go moldy when cut open they jave white grubs in. Any help would be great. Thanks. John

I would guess at Plum Sawfly

The sap leakage is caused by stress, the stress is caused by the Plum Moth maggot.
Too late to do anything about it now, but a Plum moth Trap hanging in the branches next year would be 1 solution that springs to mind.
Just hope the maggots are in one piece and not bitten in half
Hope this helps.
Your next problem is likely to be wasps looking for sugar.
Makes me sometimes wonder why we bother.
