Conquer is not labeled to be used on peach trees. You can use a product that contains permethrin but it must be labeled for use on non bearing edible vegetation such as Tengard SFR. Unfortunately once the beetles have already infested the bark of a peach tree there are not any viable treatment options. In cases of infestation the general recommendation is to simply protect the surrounding trees with preventative sprays with a product labeled for such a use.
