Bill from Schuylkill Haven, Pa writes
Tordon RTU Specialty Herbicide is best applied to fresh cut stumps, so you can either make a fresh cut or you can drill new holes and then apply. Since the active ingredient in Tordon RTU is known to leach into the soil from treated roots and can remain for several years you would need to completely replace any soil in the area before planting anything else. Untreated trees/plants can occasionally be affected by root uptake of herbicide through movement into the the topsoil or by excretion of the product from the roots of nearby treated trees. Do not apply Tordon RTU within the root zone of desireables unless such injury can be tolerated.
