Tordon RTU Specialty Herbicide
Tordon RTU Specialty Herbicide, For controlling unwanted trees via cut surface treatments in forests and non-cropland areas such as fencerows, roadsides, and rights-of-way.
Tordon RTU Specialty Herbicide effectively kills cut stumps when you are cleaning out fence lines and non-cropland areas. RTU stands for Ready-To-Use, and that's just what it is. No mixing or measuring is required, and you can use it nearly year-round. Just pour it into the convenient squirt bottle applicator, and go to work.

Tree Injection Treatment
Use 1 milliliter of undiluted Tordon RTU solution through the bark completely around the tree trunk at intervals of 2 to 3 inches between edges of the injector wounds. Make injections near ground level when using the tree injector or 2 to 4 feet above the ground when using a Hypohatchet Injector or similar device. Treatments can be made in any season. Maples should not be treated during the spring sap flow. With some difficult to control species such as dogwood, hickory, sugar maple, bigleaf maple, tanoak, and some firs, application to a continuous cut rather than to spaced cuts may be more uniformly effective.
Frill or Girdle Treatment
Make a single hack girdle or "frill" of overlapping ax cuts through the bark completely around the tree as close to the ground as feasible. Spray or paint the injured surface with undiluted Tordon RTU, using enough volume to wet treated areas.
Stump Treatment
Spray or paint the cut surfaces of freshly cut stumps and stubs with undiluted Tordon RTU. The cambium area next to the bark is the most vital area to wet.
