Is it pest or disease?

I found several white dots on a branch of flowering quince I brought home to flower. They look like small drops of lime dried. I can take them off with my finger nail. When smashed, there is something dark inside, but it doesn’t feel wet. Here is a picture of a side attached to the branch, and bellow it, external side on a thumb nail for scale. I think I saw similar once on sour cherry. Any idea what it is?


Probably an insect egg. If so I have no idea what.

Looks like an egg to me too, or maybe a cocoon of some sort?.

If it is an egg, then it is dead one - it is dry inside. It also resembles this:

But it is much whiter than on the pictures I find for san-jose-scale.

Some animal’s poop?

No, doesn’t look like it. It looks attached to the branch, and they are in numbers, but not in the same place, kind of spread. And very very small, like 1/2 mm

It could be something laying eggs desperately, not finding what they usually lay eggs on, and so compromising.

That is happening a lot, like boring beetles not finding the plants they are used to, so they try something else, like fig trees to lay their eggs inside of.

I have that on a J plum and a little on a nearby peach tree. Best I could figure is that it’s white peach scale?

Mine made very tiny little orange dots last summer is why I realized it wasn’t just part of the wood.

This article has pictures that look like mine:

Yes, it looks very close to what I have, I just don’t have it as heavy as pictured. Thanks!
