What stage should apples be to spray for bugs
Iosco County Michigan
When to spray your apple really depends on which pest you are trying to control.
Here is a link to an excellent publication from Purdue which discusses home fruit plantings and pest control. It will help you decide which pests you have and how to control them. It is a large PDF file (34 color pages with lots of pictures) so you should down load it to a computer to look at it rather than a phone.
