Chemjet is an Australian company which developed, produces and sells the Chemjet Tree injector. The injector is economical, efficient and refillable, as well as environmentally sound tool to control plant diseases by injecting trees with chemicals. Using the Chemjet injector, no chemicals escape into the environment. Disease control methods using the Chemjet Tree Injector have been successful worldwide

How It Works

The aim of tree injection is to utilise the trees natural transport system to distribute pesticides, fungicides and fertilizers to the areas where they are most effective without releasing any of these chemicals in the environment. In addition compounds can be injected which boosts the trees own defense mechanism.

The Chemjet Injector is a spring-loaded device, with a 20mm tapered 'nozzle' to assist when placing the injector into the tree. Like a syringe the chemical is 'drawn' into the 'chamber' of the injector in measured 10, 15 or 20ml quantities. The injector is then 'locked off' by turning the handle in a clockwise direction.

The injectors are placed in the tree by drilling a 4.2mm or 11/64" (wood dependent) hole 50mm deep then utilising the tapered nozzle to secure the injector firmly in place. Turning the handle anti clockwise will then release the device and inject the tree with the desired amount of chemical.

A tree's circulatory system can be likened to that of a human. The tree takes up carbon dioxide and energy from the sun through the leaves where it photosynthesis' it's food. The food (sugars and carbohydrates) then dissolve in the sap and are carried downwards through the inner bark. This food is then distributed to every living cell in the tree including the root system. Applying chemicals to the plant tissue by spraying is inefficient especially in the fight against root pathogens.

Tapping into the trees natural circulatory process allows chemicals to dissipate rapidly and effectively, minimising wastage yet maximising efficiency by distributing to vitally important elements of the tree's infrastructure.

Note the flow of the chemical as is it introduced through the trunk. The chemical reaches every element of the tree including the fine root hairs. Tree injection is also an economical alternative to other methods. The tree receives the chemical 'directly' therefore wastage is minimised.

Finally and most importantly, injecting the tree is the environmentally sound option when compared to alternate methods of treatment. Simply, a tiny fraction of conventionally used chemical is injected directly into the tree, without any release of chemicals in the environment.
