Apple trees don’t look healthy
Hi, We have 8 apple trees and last year we noticed two of them had leaves that looked like the attached images. The leaves started out looking fine, but developed this. The fruit also did not look healthy, though when we cut into the apples and eat them, they seem fine. This year most of the trees look like this. Any idea what this is? And more importantly how to avoid it next year?

For home apple grower sprays where you need to protect against insects, and diseases I recommend this short resource from the University of Kentucky https://plantpathology.ca.uky.edu/files/ppfs-fr-t-18.pdfPurdue also has a good resource for pest control, with color photos.
Thank you so much for your help! Are the apples still safe to eat even with the fungus? When we cut the bad spots off they seem to be fine inside.
The apples are fine to eat. The fungus attacks apple trees and poses no threat or harm to people or any animals. It just makes the apple ugly.
