Trunk Injection On larger trees that have a caliper of 6” and up and native species we will now be able to treat these trees with Insecticide, Fungicide, and Fertilizers. By using a Trunk injection method there will never be products sprayed in the air that have the potential to move to undesirable areas.
How does this work? AgroLawn Care creates several small holes at the base of the tree, installing a port, and injecting the desired product directly into the tree. It is essentially compared to a hospital I.V., we will inject formulations of products directly into the tree’s vascular system where it will then be distributed through the tree. The Trunk Injection techniques have become very popular over the last few years due to the safety to the environment. No more having to spray product 20’-40’ plus into the air to control insects and disease. Also because it is cheaper to care for a large tree and keep it healthy than to replace when it dies.
Why are we adding this? We are adding this to our programs due to the amount of Post Oaks and very large trees in the yards that we currently service. Also other trees that may have disease and insect problems such as Ash, Pines, Red Oaks, Burr Oaks, Live Oaks, Cedar Elms, Maples just to name a few in our area. We currently have several trees such as pine varieties in the areas that respond better to this technique than spraying products into the air. What happened to my Post Oaks and others in the neighborhood this past July? Sudden Oak Death affecting the Post Oaks is caused by the fungus Phytophthora ramorum. Phytophthora attacks the roots of trees that are in poorly drained soil or soil that becomes anaerobic due to the amount of water in the soil. In the recent years we have had significant rainfall in the cooler months of the year and the Phytophthora has stressed out the Post Oaks. Once the summer time hits and the trees need to start up taking more water, this is when the Post Oaks start showing symptoms and dying. The Phytophthora attacks the roots and the root hairs of the trees and cause the tree not to uptake the needed water, causing very rapid death. Usually in the matter of weeks during the summer or hot periods.
How long will these insecticides, fungicide, and fertilizer treatments last? For the most part, all the products used will last from 6 months to 2 years.
How are the treatments priced? Each treatment is priced by finding the caliper inch of the tree at DBH (Diameter at Breast Height, DBH is measured 4.5' from the base of the tree). A site visit is required to find this and a formal estimate will be created.
How many treatments can be made at once? We can do a combination on most trees of these products. So fertilizer and insecticide or insecticide and fungicide. We will actually come out and determine the best approach to keep your larger trees healthy.
