EZ-Ject Herbicide Lance from our sister company is easy to use and effective way to control unwanted woody vegetation – trees, stumps or brush. 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. For more information, click here.
