Tordon RTU Stump Killer Herbicide - 1 Quart

Dow AgroSciences

Tordon RTU Specialty Herbicide

Tordon RTU herbicide is a ready-to-use product that is effective in cut surface applications for killing unwanted trees and preventing undesirable sprouting of cut trees in forest and other non-crop areas such as fence rows, roadsides and rights-of-way. Tordon RTU contains blue dye to aid in keeping track of which stumps have been treated. 

Application methods:

  • Tree injection treatment: Use 1 millimeter of undiluted Tordon RTU solution through the bark completely around the tree trunk at intervals of 2-3 inches. 
  • Frill/Girdle treatment: Make a single hack girdle or "frill" of overlapping ax cuts through the bark around the tree as close to the ground as possible. Spray/paint the injured surface with enough undiluted Tordon RTU to wet treated areas.
  • Stump treatment: Spray or paint the cut surfaces of freshly cut stumps with undiluted Tordon RTU (cambium area next to the bark is the most vital area to wet).

Active ingredients:
Picloram 5.4%
2,4-dichlorophenoxyacetic acid, triisopropanolamine salt 20.9%

Not for sale, distribution or use in Nassau and Suffolk Counties in New York State.

    Just applied it yesterday. Time will tell. Followed YOUR instructions AND what I learned from watching numerous you tube videos. Cut, clean, and apply. Having done this, time will tell. I'm really hopeful that this will work as I have other stumps to deal with that will require future purchases. Thanks Seed World.

    I've used Tordon for years with excellent results. From tiny sprouts to 6"+ diameter trees. Just cut and apply and the stump is dead.
