Hi,
I live in Colorado, and this year I planted my first bare root fruit trees. Colorado State University recommends spraying all stone fruit trees 2 or 3 times a year to control the peachtree borer. Can anyone tell me if I should spray these first year trees?
Thanks,
Keith
yes, they can kill trees. (I learned the hard way)
Colorado State recommends permatgrin and cabaryl (Sevin).
Google “ Colorado State extension peach tree borers”
It has a very good article with good pictures and detailed info about different stages of borers, timing (for Colorado) and spray. Worth reading.
