How do I apply Crossbow Herbicide to kill Tree of Heaven?

This product has an attractive price point however it has a relatively low concentration of Triclopyr. What concentration of this product would be effective to kill Tree of Heaven (Ailanthus altissima) when brushed onto a stump or by using the "hack and squirt" method? Thank you


Tree of Heaven is an invasive species that can require chemical and cultural methods to control completely. You will probably need to cut a treat the stumps directly with a product like Crossbow Specialty Herbicide for best results. This article from the PennState Extension service has more information about this difficult tree.
