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.

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.

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 ...
