fruit tree spray
when and with what do you spray apple trees to stop insects from ruining the crop?
Eaton County Michigan
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
Purdue and the midwest states have a good resource on home fruit tree care.https://www.extension.purdue.edu/extmedia/ID/ID-146-W.pdf
