I have attached picture of apple trees I believe have a fungus. I need a recommendation on how to tree the trees. What to spray them with, wen to spray, and how often. Thank you for any help you can provide.

Thank you for writing.

That appears to be Apple Antracnose Canker that is fairly far advanced. https://s3.wp.wsu.edu/uploads/sites/2109/2014/12/AppleAntracnose20121.pdf

If you wish to try to save the trees, you should consult with a certified arborist to confirm the diagnosis. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
