Tree Disease and Infection Treatment Services

Like all living things, trees are vulnerable to disease. If you have many trees in your landscape, you must protect investment by keeping them healthy.

Just like diseases that affect humans, the diseases affecting trees come from infections from parasites, bacteria, fungi, and viruses.

Many of these diseases are carried from one tree to the next by way of insects. The insects that carry the disease are known as Infection Vectors.

Much of the work of preventing and curing tree diseases comes from using methods such as pesticides or introducing natural enemies to control the insects acting as infection vectors.

Another major cause of tree disease comes from malnutrition. When a plant is missing important macro or micro nutrients, it can become susceptible to all sorts of infection and disease.

This is why we perform a variety of tests including measuring nutrients in the soil. It’s also why applying proper nutrients and fertilizers help heal and protect tree health.

Our Treatment Delivery Methods

Foliar and Trunk Spray Applications

These treatments are applied directly onto the foliage of trees and shrubs when needed to help control many insects or even diseases. Certain aphids, mites, and scale insects, among others, can be well-managed with foliar applications.

Spraying trees and shrubs can also be performed as a preventative measure as well. The only downside to foliar applications is the tendency for the chemicals to drift in the wind during the application process. Depending on the chemical treatment being used, spraying may not be possible in areas adjacent to residential development.


Tree Injections

Another way to apply a treatment is to treat the roots and soil. This can often be done with an injection directly to the level of the tree’s roots.
