Most of those spots are sooty blotch. It is really only cosmetic. It should be reduced by some fungicide applications during the summer. Some are some insect stings where an insect has pierced the skin while feeding. Do you spray at all?
No, we don’t spray at all.
whst is the product which we should be spraying?
thank you so much for your help!
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.pdf
Ohio State has developed a good resource on home fruit tree care.
It is available from many states for free as a PDF. Here is one from Kentucky.
