What is a Hypo-Hatchet used for?
The Hypo-Hatchet tree injector (Figure 3) was developed as a less laborious tool for injection work. The tool consists of a modified hatchet designed to inject a small amount of herbicide when struck into a tree. Herbicide mixtures are carried in a reservoir bottle worn by the applicator.
What is a juice Hatchet?
In one lingering afterimage, a team of mostly African-American laborers, toiling in a desiccated pine forest, methodically poison sickly trees with “juice hatchets” (small axes that squirt deadly herbicide) to kill them off and make room for the planting of hardier species.
How do you use tree injectors?
The injectors are placed in the tree by drilling a 4.2mm or 11/64″ (wood dependent) hole 50mm deep then utilising the tapered nozzle to secure the injector firmly in place. Turning the handle anti clockwise will then release the device and inject the tree with the desired amount of chemical.

Can you hack-and-squirt pine trees?
“Hack-and-squirt is a very simple method,” said Jim. “If a tree has a main stem, merely place cut marks around it and inject the herbicide. However, how you make those cuts is important.” To start with, use a sharp tool such as a machete, brush axe or hatchet.
What is the hack-and-squirt method?
By Jeff Fellers Hack-and-squirt, sometimes referred to as frill-and- spray, is a herbicide application method that applies the herbicide into the stem (trunk) and is used to target specific undesirable trees. There is a slight variance between hack-and-squirt and frill-and-spray.
How do you inject a tree with soil?
Soil injection methods vary somewhat, but typical recommendations are to inject chemicals 2 to 4 inches deep with a high pressure injector either within 18 inches of the trunk or on a grid. Amounts to be applied depend on inches of trunk diameter, and diameters are added if multiple trees are being treated in an area.
What is arborjet tree injection?
Trunk injection is the most effective alternative to spraying or soil applied pesticides for tree insect or pest control. Arborjet's trunk injection equipment injects formulations directly into the trunk where it is quickly taken up by the vascular system and distributed throughout the tree.
How do you inject a tree with tordon?
For tree injection, use 1 milliliter of Tordon RTU and inject it through the tree bark all the way around the tree at ground level every 2 to 3 inches between the edges of the injection sites. Step 2: To kill tree stumps, spray or paint the solution on the cambium area of the stump next to the bark with Tordon RTU.
What kills trees quickly?
The fastest and best way to kill a tree is to make cuts in the bark and apply a tree-killing herbicide, such as Tordon. This will kill your tree in 1–3 weeks. Spraying the leaves of a small tree with Roundup or Crossbow will also kill the tree in just a few weeks. You can instantly kill a tree by cutting it down.
How long does tree injection take to work?
An effective amount of product begins adhering to the tree and working within 15 minutes of it being applied. Drying also begins within 15 minutes of product being applied.
What chemical kills trees quickly?
Tordon or concentrated Roundup is a must for killing large trees. Crossbow is great for killing trees that are small enough that you can easily spray the leaves. Patches of small trees and brush are quickly wiped out by spraying a Triclopyr blend on the bottom 12 inches (30 cm) of tree bark.
What Are Hack-and-Squirt Herbicide Applications?
Hack-and-squirt herbicide applications are one of the least expensive manual herbicide application methods. This method introduces the herbicide into the stem using spaced cuts made at a convenient height, below the last live branch, around the trunk.
When Are Hack-and-Squirt Herbicide Applications Most Effective?
Hack-and-squirt herbicide applications are effective at any time of the year, except during heavy spring sap flow or severe drought. Research has shown that hack-and-squirt applications made during periods of heavy sap flow are largely ineffective. Do not treat when trees are solidly frozen.
What Are Hack-and-Squirt Herbicide Applications Used For?
Hack-and-squirt applications are target-specific treatments generally used to control trees that are 1 inch in diameter and greater. Stems less than 1 inch in diameter are too small to treat properly. When encountered, cut or break small stems and spray the stub with herbicide solution.
Herbicides Labeled for Hack-and-Squirt Applications
Herbicides used for hack-and-squirt applications are water-soluble systemic materials, meaning they move vertically and horizontally within the tree. Numerous products have labels for hack-and-squirt applications (Table 1).
Applied Research
This section shares information from studies conducted by Penn State and the U.S. Forest Service. These studies involve hack-and-squirt herbicide treatments on four problematic species: striped maple, red maple, black birch, and American beech.
Conclusions and Management Implications
Hack-and-squirt herbicide applications allow for targeted, selective vegetation control with little danger of off-site and nontarget species damage. They are effective at controlling trees 1 inch in diameter and greater.

Trade names are used to give specific information. Penn State Extension does not endorse or guarantee any product or recommend one product instead of another that might be similar.
Application Equipment
For basal bark and directed foliar techniques, a backpack sprayer with a diaphragm pump is preferred. Piston pumps are also used, but diaphragm pump units operate at lower pressures and are less prone to leak ( Figure 1 ).
Basal Stem (Bark) Methods
Full Basal. Apply herbicide to the lower 12 to 20 inches of the stem ( Figure 4 ). Full basal works best on stems 6 inches or less in diameter and requires that the stem be completely wet with herbicide solution on all sides. A narrow angle, flat-fan spray nozzle or adjustable spray tip works well.
Cut Surface Methods
Cut surface treatments include fresh cut stump, hack and squirt, frill and spray, and tree injection. As the name implies, each method involves cutting or severing the stem and applying a dose of herbicide or herbicide solution to the cut surface. Cut surface treatments are effective from mid-February through most of the growing season.
Spot (Soil) Treatment
Spot treatment is gaining in popularity for pine release for stands three years old and older. This technique applies liquid or granular hexazinone to the soil in a regular grid pattern across the stand; however, no spots should be within 36 inches of pine stems. The backpack pump equipped with a straight stream nozzle is used.
Directed Foliar Spray
Directed foliar spraying is an effective growing season treatment as long as care is taken to avoid spraying desirable stems. The growing tips and foliage of unwanted stems are sprayed, usually with a backpack sprayer equipped with a spray wand or gunjet ( Figure 12 ). A full cone, flat fan, or adjustable cone spray tip is used.
Summary
Individual tree herbicide applications offer forest landowners a "hands-on" option to reach forest management objectives. This publication alerts readers to the many herbicides labeled for this use and discusses application technology options.
More Information is Available
Actual application rates of individual herbicides for each treatment type is well beyond the scope of this publication. However, excellent resources are available that will help you determine which herbicide to use for a given treatment and the appropriate concentrations needed.
