Hello:

Thank you for your message. The Home Fruit Spray Guide I most often refer to is from Purdue University and is online at https://www.extension.purdue.edu/extmedia/id/id-146-w.pdf

See the apple spray schedule on page 27. The most common insect problem in backyard apple trees is the apple maggot (starting in mid-June; see "second cover" spray.

Thanks.
