Can Safari 20SG be used to treat bronze birch borer in birch tees?

I have a white birch with borer holes on the trunk and foliage thinning on the top 1/3 of the canopy. What is the best method to apply? How does the effectiveness compare to other systemic insecticides?


Safari 20SG  is not labeled to treat Bornze Birch Borer. Bronze Birch Borer can be difficult to treat. You can try Merit 75.You will dilute the 1.6 oz pack in at least 10 gallons of water and pour the dilution around the base of the tree. You will need to use 1.6 oz (1 packet) MERIT 75 WSP per 24 to 48 inches of trunk diameter.
