Hi all,
Is this damage to my plums due to insect or fungus? Its affected 90% of my plums…sigh…

I have removed the affected plums
That could be insect or bird pecks.Was there any hail recently?
The first pic, there were several crescent moon marks. That is a typical wound made by plum curculio.
More than one pest love plums.
I have had a lot of birds recently, as I have overseeded my lawn…but I just presumed they would take larger chunk and/or wait for it to ripen?
As for pests/insects, I have cut them open, nothing inside…can the pests have damaged from outside only?
I am not sure about bird pecking. My fruit pecked by birds , the scars were very obvious.
Re. Spray, you can do low impacted or synthetic. The info is in the Guides category.

The curculios lay an egg in the flap of the crescent shaped scars. You wouldn’t see anything yet. The egg would eventually hatch and a tiny grub would slowly eat its way to the seed.

I have sprayed the tree.
So far, the plums I left on have no further damage…although annoyingly, they are a lot smaller than the ones I had to remove.
This feels like a war - one front is birds, another is squirrels, another aphids, another beetles/weevils…argh.
