Researchers and tree professional continue to investigate the use of systemic fungicides in an attempt to provide safe, long lasting protection against oak wilt. While there are several injectable fungicides labeled for the control of oak wilt, many researchers and professional applicators agree that Propiconazole 14.3% MEC. This formulation has proven effective for the suppression of infectious disease caused by the fungus Ceratocystis fagacearum which invades and disables the water-conducting system in susceptible trees.

With the expiration of Alamo's patent in 2005, other products, KESTREL and Quali-Pro (all are Propiconazole 14.3 MEC) are now available at a much reduced cost. (These products include, but are not limited to, Kestrel, Quali-Pro, and Alamo." )  These three fungicides, are labeled for use as a preventative and therapeutic injection. Therapeutic injections have the best chance of working in trees that shows less than 10-20% crown loss due to oak wilt. Tree injections should only be made by trained arborists or others trained in the injection techniques and diagnosis of Oak Wilt.

Micro-Injection is contained delivery system that presents the applicator with an environmentally-friendly alternative to spray and soil applications. This is a technique that injects small amounts of treatment products into the sapwood or cambial tissue through small holes drilled into the trunk flare of the tree. This is the safest and most environmentally friendly treatment method for trees because there are no hazards presented to birds, wildlife, people or friendly insects such as ladybugs and honey bees. The micro-injection system can manage and control a wide range of vascular - fungal pathogens, feeding insects, leaf sucking insect’s and nutritional benefits or other tree diseases directly into a tree without any contact to the environment.

Micro-injections have become an increasingly popular clinical alternative to the macro-injection and spray applications in the control of tree health problems. It further benefits trees with low xylem porosity that cannot accept high volumes of liquids via trunk flare injection. These new techniques has focused on developing systemic formulations of insecticides, fungicides and mineral nutrients that are very effective in low volumes, maximizing uptake and distribution and at the same time minimizing wound effects. Research started in the early 60's on micro-injection and is continuing in the direction of potential systemic uses for new health care chemicals and offering the applicator a new clinical tool for better and safer tree health care technology. The use of new and better designed micro-injection delivery systems are continuing to evolve as well and ultimately will reduce wound damage, breakage and chemical lose during applications. I have been doing an in-depth research for more that a year on the pros and cons of micro-injection versus macro-injection. Macro-injection is the procedure which we have been using for the last 15 years.         I have looked at all the various systems and procedures. I am convinced that the benefits of micro-injection far out weights many of the drawback of cumbersome equipment and the damage to trees caused by the larger drill bits and numerous drill portals required to achieve the same goal. I have had lengthy discussions with various applicators of their experience and success with the micro-injections. I feel, it is important to my customers to give them the best option, as I believe micro-injection can offer.

One of the best and most user friendly micro injection systems that is now available is the "The Chemjet®" Syringe. (Australian made) has more that twenty years of field application and is widely used throughout Australia, in Europe, the USA and Canada. Many of the injection vials are one time use disposable products, other mechanical injections systems can cost thousands of dollars.

The Chemjet® Syringe is a sturdy spring-loaded syringe, with a strong self tapping "nozzle" to assist when placing the injector into the tree trunk flares. Like a syringe the chemical is drawn into the chamber of the injector in measured 5, 10, 15 or 20 mil. quantities. The injector is then locked off by turning the handle in a clockwise direction. The injectors syringes are placed in the tree by drilling on a downward slant with a 4.2mm or 11/64" hole ¾” to 1 ¼” deep, then utilizing the self tapping tapered nozzle to secure and seat the injector firmly in place. The Injector will seat about 1/2 inch into the sap wood and it is best to drill in the shallows of the bark furrows. Note: Do not push or screw the injector nozzle all the way to the fill chamber, the thread design is only to add strength to the tapered nozzle.  Turning the handle counter-clockwise will then release the device and inject the tree with the desired amount of chemical.  ( The spring force is 23 lbs ) Here is the good part "Chemjet®" is totally reusable time after time, just dip the nozzle in Clorox, rinse and reuse, it's that easy. You may also use Lysol Disinfectant Kitchen Spray, a triple action microbial disinfectant and is non corrosive. "Chemjet®" is very cost effective, and handled properly they will last two or three years and if handled propoerly that would mean several hundreds of times of reuse. In general, uptake is about 40 to 50 min. in the tree; however, this period depends on weather, tree age, tree health, and soil temperatures. However, the material may take longer to move in stressed trees or in locations with inadequate soil moisture.

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 phloem 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 and vascular pathogens. Tapping into the trees 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.

Wound closure:There are very good research studies on wound closure. Small, shallow holes should be enough to allow us to inject the needed amount of product into the tree and cause the least amount of damage. A tree in good general healthy condition, these very small shallow wounds ( 4.2 mm  or 11/64" drill portal ) created in the drilling process close very readily and will heal within weeks.  Oaks trees generally have a higher rate of wound closure.  

Meristem   Plant tissue whose cells actively divide to form new tissues that cause the plant to grow. The originally undifferentiated cells of the meristem can produce specialized cells to form the tissues of roots, leaves, the cambium and other plant parts. The meristem includes the growing tips of roots and stems (the apical meristems) and the tissue layer known as cambium..... Meristem cells play an important role in regeneration and wound closure ...  

The Chemjet® Syringe Easy to use! All you need is a portable battery- powered drill.

  • Scientifically Proven! Chemjet® has been field tested for over 25 years. Chemjet® micro-injection is the treatment of choice for professional arborists ! Today the device is used in many countries world wide.
  • Environmentally friendly! By injecting fertilizers, insecticides and fungicides directly into the sap stream of the tree, micro-injection utilizes the tree's own natural transport and delivery system. The treatment is entirely within the tree and the dosages are determined precisely by the size of the tree. The material does not have to penetrate the soil, the leaves or the bark to be come effective, it goes to work immediately. No air, soil or groundwater contamination occurs--unlike other method, birds, fish, beneficial insects and surrounding foliage aren't harmed. Traditionally, the only way to deal with the problem was to spray the tree with pesticides and other chemicals.
  • Economical & Efficient! Micro-dosages of fertilizers, insecticides and fungicides can be pre-measured in to the chamber in dosages 5, 10, and 20 mils. No drift, no spill, no waste!  The chemical manufacturers are no providing higher concentration formulations designed specifically for the micro-injection industry.
  • Fast and Effective! Since materials are injected directly into the conductive tissues of the tree, the liquid treatment moves quickly to where it is needed most.
  • Longer Lasting. Formulation products will last up to 2 years.  The Syringes can be reused hundreds of times with proper care and handling.
  • Damage Factor! The reduced size of the drill bit from 5/16” to 11/64” and the reduced number of drill portals required for flare root macro-injection verses the fewer portals is less that half as required for micro-Injection into the tree trunk. These very small shallow wounds created in the drilling process, close very readily and will heal within weeks.
