- From the ground to a height of 12 to 15 inches, apply a band of herbicide ranging from 25 – 60 ml (0.84 – 2.02 oz).
- Spray just enough so that the herbicide doesn’t run off onto the ground.
- Ensure all sides are covered, including any aerial roots.
- Wait 45 days, then repeat the process 6 inches above the initial basal bark treatment.
How do I apply basal bark treatments?
Basal bark treatments are most easily applied with backpack sprayers or handheld pressurized spray bottles. Use an adjustable cone nozzle or a 20-degree angle flat fan spray nozzle at low pressure to prevent over application and herbicide waste. Q: What carrier and herbicides do I use? Basal bark treatments are different than foliar treatments.
What is basal bark used for?
Basal bark applications are used to control thin-barked trees generally less than 6 inches in basal diameter. It is most commonly used in hardwood forest management timber stand improvement projects to remove undesirable and invasive tree and shrub species.
What is the difference between foliar and basal bark treatments?
Basal bark treatments are different than foliar treatments. An oil carrier is used instead of water and only specific oil soluble herbicides are effective. Historically, diesel oil was used as the oil carrier. While it can still be used, newer oil carriers are safer and just as effective.
What herbicides are used for basal bark treatment?
The most commonly used herbicides for basal bark treatment are oil soluble, though some water soluble herbicides are labeled for basal bark application when mixed as a water-oil emulsion.
What is a basal bark treatment?
INTRODUCTION. Basal bark treatment is a selective method of controlling woody vegetation by spraying chemicals that are labeled by the manufacturer for the specific use on the stem (bark) of the targeted plant species. This method is useful for controlling woody plants that are too tall for foliar applications.
What is a basal oil?
Alligare Basal Oil is a low-viscosity, nonaromatic diluent that contains paraffin oil and select coupling agents and surface-active compounds. It's a type of surfactant that not only dilutes thicker products but also spreads them more easily over the target surfaces.
What is bark oil?
IN ESSENCE... Cinnamon Bark Essential Oil is the sweetly spicy and woody essence obtained from the Cinnamomum zeylanicum tree, which is native to Sri Lanka. Used in aromatherapy, Cinnamon Bark Essential Oil helps to relax, manage stressful feelings and enhance mood.
How is triclopyr applied?
Products with triclopyr can be applied aerially or by ground application. They may be applied on tree bark, injected into tree trunks or soil, or sprayed on plant leaves. Products with triclopyr may have acid, salt, or ester forms.
How do you mix diesel remedy?
Mix the Herbicide with Diesel The recommended mixture is 15% Remedy™ and 85% diesel fuel or vegetable oil (see mixing table below). Using vegetable oil instead of diesel fuel oil increases the cost but may be desirable in some situations. One vegetable oil known to mix well with Remedy™ is JLB Oil Plus™.
Does Roundup harm trees?
In short, Roundup is safe to use around trees so long as it does not come directly into contact with foliage or leaves. Seedlings, suckers, and other juvenile trees would be susceptible to damage if roots or leaves pick up Glyphosate through rain run-off or windborne spray.
Which is better cinnamon leaf or bark?
If you are seeking a sweeter and spicier aroma out of the two, Cinnamon Bark is the more potent choice. It contains more cinnamaldehyde than Cinnamon Leaf, giving it a stronger, more intense Cinnamon aroma. And if you want something even more fragrant but still smells like Cinnamon, opt for Cassia.
Is cinnamon and cinnamon bark oil the same?
The bark oil contains more Cinnamaldehyde, & has the stronger cinnamon aroma. Cinnamon bark oil is recommended by herbalists for its antimicrobial and antiviral properties, Great for diffusing.
Is cinnamon oil safe for dogs?
Many liquid potpourri products and essential oils, including oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang ylang, are poisonous to dogs. Both ingestion and skin exposure can be toxic.
What do you mix triclopyr with?
When Triclopyr 4 Brush Killer is mixed with water, it creates an emulsion that will require constant agitation. Alternatively, you can mix Triclopyr with oil instead of water. Oil will help carry the product to the roots faster than water.
Do you need surfactant with triclopyr?
It is recommended to add a non-ionic surfactant for best results but is not required per label instructions.
What is the mix ratio for triclopyr 4?
The mix rate for triclopyr is 3.2oz to 6.4oz per gallon. Triclopyr is more effective if mixed with a bark penetrent like methylated seed oil.
What Are Basal Bark Herbicide Applications?
Basal bark herbicide applications are made using a low-pressure backpack sprayer to thoroughly wet the lower 12-15 inches of the stem using a solid...
What Are Basal Bark Herbicide Applications Used for?

When Can Basal Bark Herbicide Applications Be Made?
Basal bark herbicides can be applied anytime of year, including winter months, except when snow prevents spraying to the ground line or when stem s...
Applied Research Results: Basal Bark Herbicide Application Rate Study
Traditional understory low-volume basal bark treatments using triclopyr ester have used herbicide mixtures at concentrations of 20-30 percent. Prel...
Conclusion: Management Implications
Basal bark herbicide treatments allow for targeted vegetation control with little danger of off-site and nontarget species damage. Basal bark appli...
What Are Basal Bark Herbicide Applications?
Basal bark herbicide applications are made using a low-pressure backpack sprayer to thoroughly wet the lower 12-15 inches of the stem using a solid cone or flat fan nozzle. To be effective, it is important to thoroughly wet the entire stem, root collar area, and any exposed roots.
What Are Basal Bark Herbicide Applications Used For?
Basal bark applications are used to control thin-barked trees generally less than 6 inches in basal diameter. It is most commonly used in hardwood forest management timber stand improvement projects to remove undesirable and invasive tree and shrub species.
When Can Basal Bark Herbicide Applications Be Made?
Basal bark herbicides can be applied anytime of year, including winter months, except when snow prevents spraying to the ground line or when stem surfaces are saturated with water.
Applied Research Results: Basal Bark Herbicide Application Rate Study
Traditional understory low-volume basal bark treatments using triclopyr ester have used herbicide mixtures at concentrations of 20-30 percent. Preliminary work conducted in 2006 found that much lower rates are effective at controlling most common problem understory tree species found in Pennsylvania.
Conclusion: Management Implications
Basal bark herbicide treatments allow for targeted vegetation control with little danger of off-site and nontarget species damage. Basal bark applications are well suited for treating small-diameter stems (less than 6 inches in basal diameter). They are applicable for small ownerships and steep terrain often encountered in the Appalachians.
How it works
Herbicides in oil can penetrate the relatively thin bark of smaller trees, shrubs, and woody vines. The chemical is transported by the vascular tissue to the root system, preventing regrowth. Herbicide injury may not be observable for several weeks, and the plant may not die for months following treatment (Ferrell et al. 2015).
Methodology in Detail
Low volume basal bark herbicide treatment can be conducted any time of year, but may be less effective in early spring during upward sap flow when plants are drawing material upward from the roots. It should not be conducted when the lower trunks or stems of target plants are covered by snow or floodwater.
