What is tree injection in relation to pesticides?

Tree injection is the process of placing pesticides under the bark of trees. This method is specifically designed to deliver the pesticide directly into the tree's vascular system, where it can be distributed more effectively to target pests and diseases that affect the tree. Unlike surface treatments or soil applications, tree injection minimizes the risk of pesticide runoff and non-target exposure, making it a more controlled approach.

In this method, a specific volume of pesticide is injected into the tree, often using specialized equipment that facilitates penetration of the bark and movement into the tree’s tissues. This results in a targeted application that can be particularly effective for certain pests that reside within or feed on the tree.

Understanding tree injection is crucial for those involved in pesticide application, as it highlights a more efficient and environmentally conscious approach to managing tree health.
