That’s my bet. CAR and quince rust pressure is high for me. Doesn’t look like their usual fruiting structures though.
I’m guessing that’s what got these apples, too, even though it is spread by Eastern cedar or junipers, not western red cedar. Someone could have brought home some non-native trees near me.
Only the Potomac pears have these spots. I don’t remember them during prior years. These trees have been fruiting for 4 years. First two the fruits were very green, juicy, super enjoyable. Last year they were heavily cat-faced, I think from stink bugs because we were inundated. This appears to be a new unrelated problem. Does anyone know what this is?

I searched some state extension services and think it’s San Jose scale. They all recommend dormant oil when the trees are dormant, and of course I didn’t do that.
I have the same problem on my plum and apple leaves. I wish someone could provide some inputs .
