Here is a good resource on home fruit care.
They also have a good resource for pest control. https://www.extension.purdue.edu/extmedia/ID/ID-146-W.pdf
It is very complete with a lot of basic information on pesticides before they get to the recommendations at the end of the book. Looking at this I see that it is focused on direct pests which attack the fruit. Stone fruit trees are also attacked by peach tree borers https://www.canr.msu.edu/ipm/diseases/peachtree_borer
These are controlled by trunk sprays directed at the trunk and lower branches in mid June and mid July. Look for a borer spray at the garden store or garden center where you purchase your spray materials.
Let me know if you have any specific questions
You will find looking at home fruit pesticide products that there are usually two different types of spray mixes which contain both a fungicide and an insecticide. One is a mixture of captan (fungicide), malathion (insecticide) and carbaryl (insecticide). The other is a mixture of boscalid (a fungicide), pyraclostrobin (fungicide) and lambda-cyhalothrin (a pyrithriod insecticide). Don't be confused by different trade names. Read the label it will list ingredient and instructions for use. You will see that they are limited to only 2 applications per season. I recommend using both products and alternating between the two for a total of 4 applications of the two different mixtures. There is also a fungicide product containing chlorothalonil which can be used early in the season through bloom but not when there is fruit present. I would recommend using this product until after bloom.
