Prevent drilling damage
With no drilling needed, the Wedgle Direct-Inject ™ system prevents long-term wounding, protecting tree health and vitality.
Increase effectiveness, lower costs
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 your cost per tree.
Treat almost any tree in five 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 costs and boosting profits.

- 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.
