The product label for Crossbow Herbicide does not address girdling specifically, so we would not be able to give you specific advice on this application. Per the treatment instructions for Conventional Basal Bark and Stump Applications: "...Mix 4 gallons of this product in diesel oil, No. 1 or No. 2 fuel oil, or kerosene to make 100 gallons of spray mixture. Spray the basal parts of brush or trees to a height of 15 to 20 inches from the ground...For better regrowth control, cut the larger trees and treat the stumps."
