What apple disease is this

[greyphase]

A friend has this appearing on many of his apple leaves. I’m not familiar with it. Does anyone have any ideas what it is? and how to treat.

Looks like apple scab to me

Hello, @greyphase just a guess: apple scab. Was it cool and wet recently in your locale?

[smsmith]

Agree on apple scab. Captan should help prevent it from getting worse.

Apple scab appears on the surface of the fruit also, right? Not just the leaves?

[greyphase]

Thanks for all the replys. That was my guess but wanted to confirm it. I’ll pass the info along.

Because of the dark border I would think frogeye leaf spot
