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.

    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.

    Haven't had time to use the product yet, but the buying and shipping experience was great. High shipping, but overall lower cost than other places we shopped. Would buy from them again. FAST shipping as well.

    Shame on you !!!!!!

    This product is EXTREMELY dangerous in many ways. Physically and environmentally. I want to return it for a full refund. You should not even be selling such a product.

    Excellent product. Have used to kill invasive trees in pasture and fence lines. It kills them and they have not sprouted back yet, (3 months). Easy to use and appreciate the blue tint.

    It arrived right away and was a root killer so I was worried but it was sealed and reinforced several times. Thanks for your diligence in safety of shipping a dangerous chemical.

    I started using it today on shoots of Locust trees (4) that we cut in July: The shoots are with a revenge everywhere on the property: w’ll see how Tordon will kill bad ones but not good plants and shrubs: that looks very strong! I followed instructions. Delivery very fast! Thanks
