How does the the Smart-Shot™ Refillable Tree Injector work?

The Smart-Shot™ Refillable Tree Injector allows a precise dosage to be filled in the injector and then delivered under very low pressure into the tree’s vascular system. This is done by drilling a hole through the tree’s outer bark then inserting the charged injector into the correct area and releasing the dose.

What is the difference between the Smart-Shot™ Refillable Tree Injector and other tree injection systems?

Low cost.  Low pressure (<3.5psi) as opposed to other injection systems that can cause wood tissue wounding at the injection site.  No rubber or plastic plugs need to be inserted or left in the tree.  Very small injection hole (4mm).  Immediately refillable and reusable.

How many Smart-Shot™ Refillable Tree Injectors do I need to inject one tree?

You can complete the correct dosage injection for one tree (or many trees) using only one injector, however it will be quicker and more economic to use several injectors at the one time to perform the treatment. We recommend at least four (4) injectors on trees with trunk diameters up to 500mm and six (6) on trees with trunk diameters over 500mm. When using multiple injectors, the injectors are inserted one after the other and by the time the last injector is inserted it will be time to check the first injector to determine if the tree has taken up the dosage. Multiple injection sites should be spaced evenly around the tree to provide uniform uptake.

What other tools do I need to undertake tree injection treatments?

You will need either a hand or cordless drill, several sharp high-helix 7/32” drill bits, a container to store and transport the injectors and a diameter measuring tape to calculate dosage. Personal protective equipment such as chemical-resistant gloves, eye protection and long-sleeved shirts is recommended. Please refer to the particular chemical manufacturer’s instructions for other requirements.

How do I clean the Smart-Shot™ Refillable Tree Injector?

Mauget recommends that the Injectors be cleaned regularly by rinsing and washing the injector with clean water. Apply a smear of silicon grease/spray to the plunger seal after cleaning for best results.

How long does it take to treat a tree using the Smart-Shot™ Refillable Tree Injector?

The injection process can take between 5 – 30 minutes depending upon a range of variables, including tree species, tree age, tree health and climatic conditions (temperature, wind, etc.). Avoid injecting on cold, rainy or overcast days and early mornings as this will significantly slow the injection uptake process.

Can I leave the Smart-Shot™ Refillable Tree Injector in the tree overnight or while I do something else?

CAUTION; Do not leave the injector/s or tree unattended during treatment. Pesticide applications must always be monitored and attended.

How difficult is it to use the Smart-Shot™ Refillable Tree Injector?

The injectors themselves are simple and easy to use. It is the actual drilling the tree that requires some basic understanding of tree physiology to ensure correct placement and fitting. The injection hole should be drilled on a slight downward angle with a sharp high-helix drill bit (7/32”) using very light pressure through the outer and inner bark to the sapwood (moist vascular tissue). Do not drill too deep; this will slow the injection uptake process. Injection sites should be low down on the trunk and the root buttress and not above the first limb.
