Users Guide and Parts List

Foresters, utility managers, and agricultural producers now have an efficient, effective, economical way to control unwanted woody vegetation. With one simple movement, the spring-loaded head injects a herbicide shell into the base of a tree, stump, or brush. The herbicide is absorbed by the tree, effectively killing roots, trunk, and foliage.

Easy to use, effective

  • Each ready-to-use EZ-Ject Herbicide Shell contains a small amount of chemical held in a dry, stable form within a brass shell.
  • Systemic herbicides kill the tree completely. There is rarely any regrowth or suckers. Dead tree and stump can be removed or left to decompose naturally.
EZ-Ject Herbicide Lance
  • A single compression stroke of the EZ-Ject lance head drives the shell through the bark and into the cambium layer of the tree.
  • Once in the cambium, the tree’s sap dissolves the chemical which is taken up into the tree killing roots, trunk, and foliage.
  • Fully loaded, the EZ-Ject lance weighs less than 10 pounds.
  • Gravity fed, spring-loaded head injects shells through bark with minimal operator effort.
Applicator benefits
  • Lightweight, simple to use, less fatigue.
  • Easy to use in overgrown or difficult-to-reach areas.
  • Minimize exposure risks—no mixing, measuring, or spraying.
  • Safer than chain saws—no blades, flying debris, fumes, or noise.
  • Minimal training, worry-free operation.
  • Work in any weather.
Forest and crop tree benefits
  • Selectively kill undesirable trees.
  • No off-target herbicide effects.
  • Slower canopy opening allows crop trees to adapt.
  • No disease transmission.
  • Less fire hazard than mechanical options.
Environmental benefits
  • Manage vegetation in sensitive sites without drift or spill risks.
  • Thin stands without felling. No slash to impede wildlife movement.
  • Create wildlife habitat trees, such as snags for perching birds.
  • Retain beneficial foraging vegetation while controlling unwanted trees and brush.

EZ-Ject Herbicide Shells

EZ-Ject herbicide shells control dozens of varieties of trees and woody vegetation. Shells are packaged 25 to a tube with 48 tubes contained in each 1200 shell box.

Load shells into EZ-Ject lance, screw on end cap, and begin injecting. Lance shaft contains four chambers into which shells are loaded. Fully loaded, the lance weighs less than ten pounds.

Use year-around, unless bark is frozen to the point of preventing shell penetration. Use in all weather conditions, including rain.

Insert one shell every two to four inches around the circumference of the tree. See chemical labels for details.
