Hi Terry,
Here's the updated peach tree borer fact sheet: https://extension.colostate.edu/resource/peachtree-borer/
The current insecticides are permethrin or carbaryl.
But the most important thing you can do is boost the overall health of your tree and prevent stress. Be sure to water your tree, mulch, and do proper pruning.
