Professional tree care use several methods to control tree pests. Spraying has been the most traditional approach. However, this method has several disadvantages with concern for environmental impacts.
Tree injections and implants can be effective against certain kinds of pests. These types of treatments use less volume of material and what is applied, goes directly into the tree.
One popular injection system is called a Mauget Injection.
Mauget injections are actually a system developed in part by Jim Mauget, that helped establish the JJ Mauget Company in 1956. His patented system provides the ability to administer fertilizers, pesticides, and other products directly into the tree's vascular system without the need of having the roots absorb a treatment through it's root or leaf structure. This reduces the need for spraying and root injections.
Mauget injection is actually a micro-injection directly into the plant. This applies fertilizers, insecticides and fungicides directly into the sap stream of the tree without contaminating the soil, air or groundwater.
Mauget injections are an environmentally friendly way to apply pesticides to trees. No need to worry about drift, because of the patented closed system this means the chemical is contained entirely within the tree. Only pests feeding on the tree are directly affected. Beneficial and non-target insects and other life forms are not affected. This gives the applicator the opportunity to treat trees in adverse weather conditions.
This controlled application protects our environment, but also protects birds, fish and beneficial insects in a way that they aren't harmed, yet the problem areas are addressed where they're needed the most.
These injections must be applied at the right time of the year for the most benefit.
The system is a very effective method for combating nutrient deficiency, disease and fungus control. With no unnecessary overspray and rain washed wasted material. The method is done by drilling small holes into the tree at the root flare and installing capsules every 6" around the base. The material is then dispersed up the tree from the sap.
Extreme caution is required when drilling holes so that damage to the tree is limited. The hole should only penetrate the outer 2 layers of the tree. Deeper holes may not heal properly. Never re-apply this type of product to a tree that has been previously treated with holes that have not healed.
