Tempo SC Ultra should not be applied to edible garden areas/crops. Current insecticides useful for this treatment would include products that contain bifenthrin (Talstar), cyfluthrin (Tempo SC Ultra) or permethrin ( Tengard SFR). Rates of use should be to the high-end of what is labeled, such as for bark beetles or borers. Timing is very important but difficult to determine. Sprays should be applied shortly before adults begin to feed on the terminal and lay eggs. You can contact your local cooperative extension office and speak to the master gardener on staff who can help you determine the correct timing.
