How the tree injector
works
The aim of chemical injection is to utilise the trees natural transport system to distribute pesticides, fungicides and fertilisers to the areas where they are most effective, without releasing any of these chemicals into the environment.
The Chemjet® Injector is a spring-loaded device, with a 20mm tapered `nozzle' to assist 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 a 4mm (wood dependent) hole 50mm deep, utilising 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.
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) 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.
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. 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 chemical is injected directly into the tree, without any release of chemicals in 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. The Chemjet® Injection system is the only low pressure system available.
To determine the correct quantity and concentration of chemical, it is recommended to follow manufacturers guidelines.
