What is the method called for delivering systemic pesticides directly into trees?

The method for delivering systemic pesticides directly into trees is known as tree injection. This process involves using specialized equipment to inject pesticides directly into the vascular system of the tree. By doing this, the pesticide becomes part of the tree’s circulatory system, allowing it to be transported throughout the entire plant, thereby providing effective control against pests and diseases that may be targeting the tree.

Tree injection is particularly beneficial for treatment because it minimizes the exposure of non-target organisms and the environment to pesticides, as the chemicals are delivered right where they are needed, often resulting in lower overall usage.

In contrast, methods such as soil drenching and foliar application involve either applying the pesticide to the soil or spraying it onto the leaves, which may not always ensure that the chemical reaches the internal tissues of the tree as effectively as tree injection does. Aerial spraying covers a larger area but also disperses the pesticide into the environment rather than targeting it directly into the tree's system. Therefore, tree injection stands out as the most direct and efficient method for systemic pesticide application in trees.
