Chemjet Injection Kit



Chemjet Injection Kit

The Chemjet Tree Injector is an inexpensive reloadable syringe used to inject pesticides, fungicides and fertilizers to treat diseases and pests, to prevent death of the tree. These injectors are used in a process called microinjection to treat an entire tree (leaves to roots) by deploying multiple Chemjet® Injectors evenly spaced around the trunk of the tree. Made of rugged plastic, the Chemjet® injectors can be reused for many years.

The Chemjet is a spring-loaded syringe-like device, with a 20mm tapered nozzle. The chemical is drawn through the nozzle into the chamber of the injector in measured 10, 15 or 20ml quantities. The injector handle is pulled back to energize the spring pressure can be locked open at 20 ml by twisting the handle in a clockwise direction.

Holes are drilled into the tree using a 11/64 bit to a depth of about one inch, and the Chemjet® nozzle is pressed into the hole by hand (no hammering) to make a tight seal.  Note: you do not have to twist while inserting!   While holding the Chemjet® in place, the red handle is pulled back slightly then turned counterclockwise to allow the spring pressure to inject chemical into the tree. The injector is then left unattended to inject at a steady low pressure of about 20 PSI which does not damage the inner bark layers, and allows discharge of chemical into the xylem at a rate that is accommodated by the natural capacity of the tree to accept more liquid.
