Tordon RTU Specialty Herbicide could be used on cut stumps or hack girdle as directed on the product label.
Because Tordon RTU Specialty Herbicide is a ready to use herbicide it should not be diluted. Doing so may decrease its effectiveness.
Tordon RTU Specialty Herbicide is not labeled for Schefflera trees. Schefflera actinophylla is very invasive and hard to kill. We do not carry products labeled specifically for it. An article from the US Military’s Integrated Natural Resources Management Plan states that Garlon 4 has been used in some instances and proved to be effective, although it is not labeled for it. We would recommend speaking with your local master gardner for more recommendations.
Tordon RTU Specialty Herbicide is ready to use and does not require mixing. However, it should not be applied to commercial or residential lawns or near ornamental trees and shrubs.
Tordon RTU Specialty Herbicide can be applied via tree injection, frill or girdle treatment, or stump treatment as directed on page 3 of the product label. Frill or Girdle Treatment is the closest to what you are describing. Per the label:
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.
There is a complete list of woody plants controlled by this product on the label. Be sure that your target plants are included on this list and that the herbicide is applied immediately after cutting for best results.
Unfortunately, Tordon RTU Specialty Herbicide is not labeled for scotch broom. You could use a product that we have called Crossbow Specialty Herbicide. Per an article from Oregon State University Extension Service this product would be effective.
Tordon RTU Specialty Herbicide is not labeled to control Wisteria, so we do not recommend it for this application. Keep in mind, too, that Tordon is not approved for use on residential properties at all. You could use a brush killer such as Crossbow or Fertilome Brush and Stump Killer to control wisteria vines.
Tordon RTU Specialty Herbicide does not list that it will work for Chinese Tallow Trees. There is a guide here that might help.
Tordon RTU is not labeled to control mulberry, so we would not recommend using this product to control it. We would recommend cutting the mulberry that you want to kill and treating the fresh cuts with Fertilome Brush and Stump Killer at full strength brushed onto them.
Tordon RTU Specialty Herbicide does not list Indian Laurel as a controlled tree. It does appear that these are best treated when they are small and not fruiting. You can try something like RoundUp QuikPro applied to the cut stump but if they are large trees it might be best to contact a tree removal company. You would need to wait 2 weeks before removing the stump.
Tordon RTU Specialty Herbicide is labeled to target the following woody plants: ailanthus, alder, aspen, birch, cedar, cherry, dogwood, elm, firs, green ash, gum, hawthorn, hickory, hornbeam, maples, oaks, pecan, persimmon, serviceberry, sourwood and sweetbay. It does not specifically state Hackberry-Silver Maple Saplings on the label, however it has Maples in general in trees covered. If the root system is hearty, you will want to cut the saplings down as low to the ground and you can get them. Once cut, immediately apply the brush killer either by spraying it on, or paint it on undiluted. Please let us know if you have any other questions.
Tordon RTU Specialty Herbicide should not be applied to commercial or residential lawns or near ornamental trees and shrubs.
Tordon RTU Specialty Herbicide is not labeled specifically for acacia trees, so we cannot say for certain that it would control this plant. However, the active ingredients in Tordon RTU are used frequently for treating cut stumps of difficult brush. This guide from the UC Davis Extension has more details about treating this plant.
Tordon RTU Specialty Herbicide is not labeled for sandbur.
Tordon RTU Specialty Herbicide does not list Camphor on the product label as controlled. We apologize but do not have anything labeled to be effective against this type of seedling. I was able to find an article here that states mowing or removing is best on the seedling trees and that glyphosate is effective it just may take a few applications. Care should be taken to avoid contact with any desirable grass/plants/trees in the area when using it
Tordon RTU Specialty Herbicide is not labeled to control Indian Rosewood. This product should not be used on any residential areas since it has a very long half-life and can remain in the soil for years after it is applied. For cut stump tree or vine treatments, you could use a triclopyr product such as Fertilome Brush Killer applied directly to the fresh cuts at full strength using a paintbrush or sprayer.
The new tree planting would need to be well outside the root zone that has been treated with Tordon RTU Speciality Herbicide. The product label states: Untreated trees 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 desireable trees unless such injury can be tolerated.
