Hello,
There are several leaf spot diseases that affect maples and often are quite harmless. I’ve included a link that informs. For accurate diagnosis of leaf spots, send plant samples to the Diagnostic Services Lab on the MSU campus. The lab will be able to identify the pathogen and provide correct treatment recommendations for the particular leaf spot on that plant. Often with many leaf spots, no treatment is necessary.
Good luck!
