Injections are a method of targeting a precise application of pesticides, plant resistance activators, or fertilizers into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies. This method largely relies on harnessing the tree's natural system to distribute the active compounds into the wood, canopy and roots where protection or nutrition is needed.
Tree injection is currently the most popular method for control of damaging insects, pathogens, and nematodes in landscape tree care.
Why not just spray the tree?
Tree spraying is harmful to the environment! Any time you spray the tree with a pesticide all the chemicals can make their way into a water source, such as a river, ocean, or pond.
Another way pesticides can spread and cause potential harm is by volatilization. Volatilization occurs when a pesticide turns into a gas or vapor after it has been sprayed, allowing it to travel through the air and spread to different pieces of land. Not only are pesticides dangerous to the environment, but they are also hazardous to our health!
The main reason however is because they really don’t work that well! Spray only reaches the top surface of the tree and it can be quickly washed off by rain which we are not short of in our area!
Tree injections, on the other hand, are so much more effective! Injections are placed directly into the tree, limiting any impact to the environment around you! The tree absorbs it all within a couple of days and starts working. There is no waste and no pollution!
