Pears and peaches and cherries use many of the same sprays as they face some of the same issues as apples but with that said there also some issues with spraying some other fruits besides apples but with the sprays I use I don't have that issue. I use Captan, Imidan, Sovran and sometimes Sevin along with dormant oil and maybe a copper spray early in the season. The only issue I have for instance is that the Sovran can cause problems with some varieties of Asian pears so I don't spray it on most of my pears and use only the Captan to hopefully take care of those issues. Research and read labels to better understand what to spray
