TRUNK INJECTION

Trunk Injection

            Trunk injection is the most effective alternative to spraying or soil applying pesticides for tree pest control. Arborjet trunk injection equipment injects formulations directly inside trees. With over 10 years of research and development, our trunk injection systems and formulations are proven to give the best results when protecting trees from pests.The Arborjet drill-plug-inject method is easy to learn and application is quick. The Arborjet trunk injection system is a perfect fit for the do-it-yourselfer but is best applied by a professional, especially for more serious problems.Unlike spraying or soil applications, Arborjet's system injects directly into the tree, limiting any impact to your family, the applicator, and the environment around you.

                  Trunk injection of trees is a way to efficiently treat many different insect and disease problems, as well as nutrient deficiencies, in a manner that limits environmental exposure. This method also uses the least amount of pesticide as compared to other conventional treatment methods. Trunk injection involves using a special injection tool which places and seals the insect control directly into the trunk where it is quickly taken up by the vascular system and distributed throughout the tree. Through trunk injection, small doses of insect control are carefully measured and injected directly into the tree’s transport tissues, enabling distribution within the tree, but limiting the impact to the environment. The best time to treat Ash trees in the upper third of the country is from May through October when trees are most active, and water or nutrients are actively flowing in the tree. The larval (damaging) stage of EAB does its worst from August through October. Injections are made in the bottom 18 inches of the tree, at intervals of around 6 inches apart. The depth for the injection is between 5/8” and 1 5/8” into the tree. A 10 inch diameter tree would receive approximately a 1.5 ounce injection for two years of protection. Trunk injection formulations can take hours to weeks to move throughout the tree. Most often trees are protected within a few days.

                Trunk injection is widely considered to be the most effective and consistent method available for preventing EAB from attacking a tree, or killing EAB in an infested tree. It can stop damage even if the tree is already under attack without harming the surrounding environment.

Researchers at Michigan State, Ohio State, Purdue, the University of Illinois, and University of Wisconsin have concluded that Arborjet’s trunk-injected systemic insecticides are the most effective treatment options, providing very effective control of EAB for two years, with a single application, even under heavy infestation pressure. It also provided a higher level of control than other products in side-by-side studies.The largest Midwestern cities, including Chicago and Milwaukee, chose and are currently using Arborjet’s trunk injection with its two years of protection, for over 115,000 boulevard trees, following careful evaluation of the alternatives.
