Q.What Is This On My Apples?

Zone 15224 | CarmanAvenue added on July 4, 2022 | Answered

I’ve always had problems with the leaves on my apple tree, but this is the first year I’ve had more than 10 apples, and some of them are in pretty bad shape. Can anyone tell me what this is?

I see two issues! The first is Black Rot or Botryosphaeria. That is the disease that is on the apple skin. There is another that is eating that contaminant. Likely Stemonitis species.

This is an interesting situation, but if you deal with the Black Rot, then the Stemonitis will go away.
