How it Works

The aim of chemical injection is to utilize the tree’s natural transport system to distribute pesticides, fungicides, and fertilizers to the areas where they are most effective, without releasing any of these chemicals into the environment. The tree takes up carbon dioxide and energy from the sun through the leaves where it photosynthesis its food. The food (sugars and carbohydrates) dissolves in the sap and is carried downwards through the inner bark. This food is then distributed to every living cell in the tree including the root system.

Tapping into the tree’s natural circulatory process allows chemicals to dissipate rapidly and effectively, minimizing wastage yet maximizing efficiency by distributing to vitally important elements of the tree’s infrastructure. The chemical reaches every element of the tree including the fine root hairs.
Applying chemicals to the plant tissue by spraying is inefficient, especially in the fight against root pathogens, and a tiny fraction of conventionally used chemicals are injected directly into the tree, without any release of chemicals into the environment.

Other tree injection systems use high pressures, which can lead to cell damage around the injection site, impair sap flow and uplift the bark. Also, the higher pressures place the product into areas where the product is ineffective and wasted. The Chemjet® Injection system is a safe low-pressure she Chemjet® Injector is a spring-loaded device, with a 20mm tapered `nozzle’ to assist in placing the injector into the tree. Like a syringe, the chemical is `drawn’ into the `chamber’ of the injector in measured quantities up to 20ml. The injector is then `locked off’ by turning the handle in a clockwise direction. The injectors are placed in the tree by drilling an 11/64″ or 4mm (wood dependent) hole 1 1/4″ or 50mm deep, utilizing the tapered nozzle to secure the injector firmly in place. Turning the handle anti-clockwise will then release the plunger and inject the tree with the desired amount of chemical.
