Reports have come in recently of both Japanese beetle and June Beetle feeding on peaches. The best materials are Danitol and Carbaryl, both with a 3 day pre harvest interval. There are no great options with a shorter PHI. Pyrethrins have a 0 day, but they tend to annoy and knock down but not kill.
Stink bug counts in blacklight traps are moderate. Consider bifenthrin around orchard edges to keep them out, especially of apples.
