What is basal bark treatment?
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. These are called basal oils or bark oils and are formulated to maximize herbicide penetration through bark. These oil carriers are not available in retail garden centers but can generally be purchased through farmer co‐ops and pesticide distributors.

What is an oil carrier?
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. These are called basal oils or bark oils and are formulated to maximize herbicide penetration through bark.
Do you need a surfactant for basal bark?
Surfactants are not required for basal bark treatments. However, a spray indicator, such as a colorant or dye, may be useful to see what has been treated. Some basal oils that already have a spray indicator included are available.
What herbicides are used for basal bark?
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. When choosing a systemic herbicide, a site manager should consider the site characteristics, the species being treated, and the environmental behavior of the chemical relative to long-term goals for the site.
What is basal bark herbicide?
Basal bark treatment is a woody invasive plant control method that involves spraying herbicide or herbicide mixture carried in oil onto the stems bases of target plants. It is generally only effective on plants with a diameter at breast height of 6” or less (Jackson 2017).
How does herbicide work?
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).
Can you use herbicide dye on basal oil?
Specialized basal oils usually come pre-mixed with herbicide dye. If the carrier oil is used is colorless, herbicide dye is a recommended addition to the mix. Use of a dye will allow applicators to ensure complete coverage of stems, more easily recognize blow-by, track which stems have been treated, and can also alert any other site users that an herbicide was recently applied.
Can basal bark be repeated?
Any invasive species treatment needs to be monitored for effectiveness and for invasive species re-growth in the years following treatment. Basal bark treatments can be repeated if necessary, though herbicide label-specified annual limits must be followed.
What oils are used in herbicides?
These include diesel, kerosene, fuel oils, methylated seed oil, crop oil, and specialized basal oils. Always consult the herbicide product label to ensure use of appropriate carrier oil.

What Is Basal Tree Rot?
Decay in trees is often a hidden problem that takes place inside the trunk or roots and may be difficult to see. Many homeowners see a tree with a full canopy of green leaves and assume the tree is “healthy”.
Symptoms Of Basal Tree Rot
Mushrooms at the base of a tree are a strong indicator of internal decay. The tree may also lose its vigor and experience yellowing leaves and leaf loss. Infected wood may also be streaked and you will see a sharp difference between healthy and rotted wood.
Treatment Of Basal Tree Rot
Basal root rot can be prevented through correct planting practices, vigilant care that includes avoiding overwatering and overcrowding, and tree varieties resistant to fungal rots.
What is the best way to control a large tree?
The hack-and-squirt technique is ideal for control of larger trees that limit the use of basal applications. This inexpensive but labor-intensive method requires a small ax, machete, or hatchet to cut through the thick bark and into the sapwood. The cuts should create a “cup” to hold the herbicide solution and should ring the entire circumference of the tree.
How to use foliar spray on a tree?
A foliar application directs the herbicide/water mixture directly onto the leaves of a tree or shrub . This treatment is highly effective on smaller understory plants that can be mechanically sprayed over the entire leaf area. Use a foliar spray to remove undesirable understory plant competition (privet under pines) or as a single species control in patches of undesirable trees and shrubs.
What is Tsi in timber?
This form of timber stand improvement (TSI) uses soil herbicide uptake by a tree's root system to do the job. It demands an area where mechanical equipment can transport and spray, or broadcast, the chemical effectively.
When to apply soil herbicide?
Applying soil herbicides as a total treatment broadcast tool or when spotting compact areas can be quickly applied and cost-effective on large acreage. This treatment is useful when treating an area with a high density of small stems needing total control (for example, sweet gum sprouts under loblolly pine ), and also to remove individual specimens (such as undesirable tree sprouts and stems on productive timberland).
What is foliar spray?
Use a foliar spray to remove undesirable understory plant competition (privet under pines) or as a single species control in patches of undesirable trees and shrubs. This form of timber stand improvement uses a spray herbicide applied to saturate a tree's canopy and leaves.
Who is Steve Nix?

Updated June 29, 2019. Controlling woody-stemmed plants that are unwanted in the landscape can become an impossible task.
Can you spray herbicide on stumps?
Adding a dye to the herbicide formulation improves application success by showing exact stump coverage. Small stumps should be completely saturated.
What is basal bark treatment?
Basal bark treatments make sense where there are long stretches of low-density brush with stems of 6 inches in diameter or less or areas where the density may be higher but are in patches more easily accessible during the dormant season. Situations in which basal bark treatments are a good choice include: sites that are inaccessible to heavy equipment; sites that require routine but not intensive maintenance; areas where desirable vegetation surrounds target brush; and as a follow-up on a reclamation treatment. Another advantage of dormant-season basal applications is that public visibility and complaints can be minimized because foliage brownout is minimal. Basal treatments using Garlon® 4 Ultra specialty herbicide are generally one of the most effective treatment methods for targeted IPTs, and form the foundation of any tank mix for basal bark applications. This method is effective throughout the year as long as the ground is not frozen or the bark is not saturated with water. Apply a mixture of 20 percent to 30 percent Garlon 4 Ultra in commercially available basal oil, or diesel fuel or kerosene can be used.
What is a cut stump?
Cut-stump, or cut-surface, treatments also are ideal for lower density infestations and especially where selectivity is a key objective. Cut-stump treatments are perfect where individual trees need to be removed in highly visible areas and unsightly/hazardous standing dead trees are not a sensible option. In situations where desirable species are mixed with undesirable species in close proximity, cut-stump applications allow targeted control of the undesirable woody plants without danger of damage to adjacent plants because only the treated stems are controlled. Cut-stump treatments can be made anytime of the year; however, see the caution note below about tree species known as “bleeders.” Capstone™, Garlon® 3A, and Garlon 4 Ultra specialty herbicides are effective products that can be used as cut-stump treatments. The treatment options for cut-stump applications are listed below.
