Instructions For Use
Easy To Use - On Hands Trainning
1. The Trunk and Limbs from 2 inches and thicker can be used for injections
2. Draw chemical into injector by pulling the Red T handle to the required dosage with a stretched arm and lock handle with a 1/4 turn (Fig. 1). Note: The Syringes should not be preloaded and placed in the lock position for an extended period of time. The spring force may damage the lock position slot. It is best to use the product filled syringes in a minimum time following preloading.
3. Drill appropriate number of holes into tree, between the bark furrows on a slightly downward angle ( Drill bit use 4.2mm 11/64") and drill 3/4" - 1 1/4"deep. Inserting the injectors as you move around the tree.
4. Insert injector nozzle with a firm push into pre-drilled hole. Release Red T handle with 1/4 turn.
Note: The injector nozzle will seat within 1/2" into the sap wood and the screw thread effect is for added strength for the nozzle. If weeping occurs, with the open palm of your hand give the red handle a firm, but gentle nudge and you will hear the syringe seat a little deeper, to obtain a complete seal.
5. Completed injection time approximately 25-45 minutes, using potassium phosphite, varying in weather conditions and sap viscosity. When injection is slowing down, leave the injector to the following day. For the oak wilt, treatment time is normally 3 -5 hours, but don't hesitate to leave the injectors in for over night.
6. CARE & MAINTENANCE - (See Fig. 2 & 3) Wash regularly with clean hot water. ( 95 + degrees F ) Apply smear of silicon grease/spray to barrel. As you sterilize your drill with Lysol disinfectant also spray the injector tips for added security, it is not necessary, but it may make you feel better.
7. To determine the correct number of injections, quantity and concentration of chemical to be given, follow manufacturer's recommendations. By Rule of Thumb: FOR OAK WILT TREATMENT: One injector with 20 mils of product with a 50-50 solution with water. Space the Injectors evenly around the trunk stem 3 inches apart, which is the equivalant of one injector per diameter inch. FOR S O D TREATMENT: Use a 30% solution of Potassium Phosphite and space the injectors 4-6 inches apart around the trunk from knee to waist high. Caution: Do not inject the full strength Poassium Phosphite, it can and will cause serious cambium tissue burn.

How it Works
Food for the tree (mainly carbohydrates and sugars) is formed in the green chlorophyll containing tissues of the tree's leaves by a process called photosynthesis. During photosynthesis, a chemical process requiring the presence of sunlight, carbon dioxide from the air is combined with water and elements from the soil.
Respiration is a metabolic process by which the tree uses a portion of the food manufactured through photosynthesis. The food is oxidised in the living cells of the tree releasing the energy for the tree's life support systems.
A tree normally photosynthesis by daylight hours and respires at night. The raw materials, water and nutrients move upwards from the roots through the sapwood to the leaves. The tree makes up Carbon Dioxide and energy from the sun through the leaves where it photosynthesis its food. The food (sugars and carbohydrates or solutes) then dissolve in the sap and are carried downward through the inner bark. (The Pholem) The food is then distributed to every living cell in the tree including the root system.
The aim of tree injection is to use the tree's natural transport system to distribute pesticides, fungicides and fertilizers to the areas where they are most effective. For example; in order to effectively fight root rot in avocado trees, the phosphonate fungicide used needs to reach the roots, the same goes for the treatment for Oak Wilt. These chemicals are systemic and will move up the vascular system to the leaves and mix with the soultes produces by photosynthesis and then delivered via the pholem to all points in the tree where it is needed.
The Chemjet tree injector allows the tree to take up the fluid in the natural sap flow and carry it to the affected areas. This is done under gentle pressure through a spring force of 23 psi.
Injection under too great a pressure can lead to cell damage which may impair the sap flow thus preventing the chemical from reaching the affected areas. High pressure injection may also be counter productive as the chemical can be forced into the tree when the tree is not ready to absorb it. The tree will only take up fluid during the respiration stage of its metabolic process. Word of Caution: Make sure your drill bit does not get too hot. The super hot drill bit will cauterize the sap wood tissue and render the injection portal useless.
INSTRUCTIONS FOR USE, CARE & MAINTENANCE. Chemjet Tree Injector
Environmentally Friendly Tree Injector - Saving One Tree at a Time
1. Wear eye protection and gloves
2. Highspeed cordless drill
3. 11/64" (4.3 mm) normal steel drill bit
4. Select injectable product
5. Mixing container
1. Prepare the solution and dilute according to the label
2. Draw the product up into the syringe and 1/4 turn will lock the Red plunger handle
3. Drill the holes in the trunk on a slight downward angle to a depth of 1 1/4" to 1 1/2" deep spacing the syringes 4-5 inches apart around the trunk from knee to waist high, inserting the injectors as you move around the tree.
4. Push the Injector nozzle firmly into the hole and with a 1/4 turn, unlock the Red T handle NOTE with the open palm of your hand give the Red T Handle a slight, but firm nudge to ensure a tigh seal. The syringe will seat within 1/2' from the tip and the screw thread is designed only for strength.
Now the injector will start the safe and environmentally friendly process. Your tree will slowly absorb the product within 5 - 45 min with the help of the 23lb force spring. Without any harm to the xylem or sap wood tissue. It is best to inject early in the morning when the tree is most actively transpiring. Usually around 11.30 am the tree will shut down to conserve its water. If the injectors are not completely empty your can leave them over night. There will be the occasion that an injector will not empty and you may have to drill another hole. Sometimes the drill may be to hot and will burn cauterize the tissue.
At the end of the day rinse the injector in hot water with a disinfectant (Not Clorox) You can use Consan 20 disinfectant. 1 oz per gal or spray the nozzle with Lysol disinfectant spray after rincing. (Lysol contains Consan 20 and it is non corrosive) Put the injector tip into the solution and pulling up and down the plunger a number of times.
Discharge the barrel from any water, then pull out the plunger handle and set in the lock position. Then squirt some silicone spray into the barrel from the the red handle end. Unlock the plunger and pull back a couple of times, Now the injectors are ready to use again. Always start early in the morning.
