DIRECT INJECT SYSTEMS

Use Direct-Inject System - the only no-drill tree trunk injection method that is easy, fast, proven effective and tree friendly.

Prevent drilling damage

With no drilling needed, the Wedgle Direct-Inject System prevents long-term wounding, protecting tree health and vitality.

Increase effectiveness

The Wedgle Direct-Inject unit injects chemical directly into the cambial zone, right where the tree can use it. You get proven results from less chemical, lowering cost per tree.

Treat almost any tree in 5 minutes or less

No power, drills, or pumps needed. There is no guarding trees, no waiting for uptake. You’ll treat more trees in less time, reducing labor

Direct-Inject by ArborSystems
  • Inject chemical through bark only without damaging sapwood (chemical in cambial zone dyed red for visibility).
  • Inject chemical directly through the bark without drilling. No air enters the sapwood, so chemical is readily absorbed.
  • Vascular system is undisturbed, maintaining nutrient movement.
  • Chemical is placed in the cambial zone, where it is used most effectively—you’ll see improved results from less chemical.
  • Multiple or annual treatments can be made without injuring the tree.

  • Drilling for injections allows air
  • into the sapwood, disrupting translocation and reducing chemical effectiveness.
  • Air entering the vascular system disrupts nutrient movement.
  • Drilled holes often extend beyond active layers, so chemical is lost in non-active wood where the tree cannot use it.
  • Drilling wounds cause permanent damage. Repeated drilling can seriously impact tree vitality.

WEDGLE DIRECT-INJECT

Use Direct-Inject System — the only no-drill tree trunk injection method that is easy, fast, proven effective and tree-friendly.

The Wedgle Direct-Inject System is the fast, effective, tree-friendly way to treat trees for a broad range of destructive pests, harmful diseases, and nutrient deficiencies including Hemlock Woolly Adelgids, Emerald Ash Borers, psyllids, aphids, Oak Wilt, Dutch Elm Disease, Anthracnose, chlorosis and more.

Wedgle Direct-Inject Injection Unit

Two Quick-Connect (QC) couplers provide super-fast setup.

Quick-Connect Chemical Packs

The top QC coupler lets you quickly attach chemical packs to the injector.

Quick-Connect Injection Tips

The front QC coupler accepts a variety of injection tips for treating hardwoods, conifers, and palms.

Preset application rates

The injector is preset to release 1 ml of chemical with each full stroke of the handles. Easily adjusts to deliver .5 ml dose

Easy to use and maintain

Sealed injector will not lose prime while in use. Annual maintenance limited to O-ring replacement.

Closed system

Virtually eliminates exposure concerns. No mixing, no caplets, no spraying or soil drenching concerns.

With no drilling required, the Wedgle Direct-Inject System:
  • Minimizes wounding to keep out fungi, bacteria and insects.
  • Prevents air from getting into the tree. When air is allowed into a tree's vascular system, it cuts off the flow of water and nutrients.
  • Allows multiple treatments without damaging the tree.
  • Requires no drills, power supply or other bulky equipment.
  • This system lets a single operator achieve season-long control in just seconds per injection site, with a treatment method designed to protect tree vigor and prevent long-term wounding. Accessories and carrying case included free with standard unit purchase.

  • Injection tips which snap on to the front QC coupler (B)
A variety of injection tip designs let you treat more types of treesAccessory Tips

Specialized Quick-Connect Injection Tips are designed to work with trees of various bark thickness and to place chemical precisely where each tree’s unique vascular structure can best use it. No drilling is required with any Quick-Connect Injection Tip.

Wedgle Injection Tip for Hardwoods See How-To Videos

The original Wedgle Tip is the best choice for treating most hardwood trees. The wedge-shaped tip end deposits chemical where it can most easily be absorbed by the tree, in the cambial zone between the bark and outer ring of sapwood (the xylem). Choose from two lengths depending on bark thickness.

The Wedgle Tip is inserted while attached to the Wedgle Direct-Inject unit and is used with WedgeCheks (included with chemical purchase) which are small plugs that keep the chemical in the tree after the injection is made.

Portle Injection Tip for conifers and hard-to-treat hardwoods

Portle Tips have multiple “ports,” ports, or openings, along the end of the tip which deliver chemical numerous points in the inner active layers of conifers, and allows you to inject more chemical at each injection site when desired. A check valve in the base of each tip keeps chemical in the tree until it is absorbed.

Portle Tips have also proven beneficial when injecting tough-barked hardwoods such as hackberry and hickory, thick-barked hardwoods such as elm and eucalyptus, or when the bark of any type tree becomes harder to penetrate when making late summer or fall injections. The short Portle Tip works well for injecting Sycamore and London Plane trees that can be difficult to inject with the Wedgle Tip.

The Portle Palm Tip has a pointed end that aids the tip in getting into the toughest plants. The chemical ports are recessed to minimize plant material from clogging the tip. It is designed to penetrate a palm's outer husk and deliver chemical into the inner active layers. Some palms require a starter or pilot hole to be drilled so injection tips can be easily inserted through the husk.

Tip Setter

The Tip Setter is used to set and remove Portle and Portle Palm Tips. The Tip Setter is used to drive these heavier injection tips deep into the active areas of conifers and palms, or through thick, tough outer bark of some hardwoods.
