TRUNK INJECTIONS – SAFE AND EFFECTIVE Maureen Sexsmith-West ISA Certified Arborist, PR4600A

Insects can be quite damaging not to mention annoying. They are indicators of other problems with the health of your plants. As always, I recommend you address the root of the problem before considering pest management products. Adjusting your watering habits, avoiding construction activity around trees and having your tree pruned regularly should be the first part of any pest management plan.

For example, aphids produce a sticky substance called honeydew that serves as a lure for ants and wasps. Dust sticks to it creating a sooty appearance to everything. Washing off your surfaces can help and using a jet spray with your garden hose can dislodge them temporarily. Some insects, like coulee gall adelgid which causes a swelling of new shoots on spruce trees, can be pruned or picked off. Other insects, however, can cause extensive damage and result in tree mortality. Many people object to using chemicals in their yards. While there are some biological controls such at BTK and insecticidal soap, all these have to be applied by spraying. Every surface around the tree is subject to the drift and dripping this process creates. Rinsing is often required before reentry of use areas.

In February of this year, Health Canada approved trunk injections to control specific pest issues. The great feature of this method is A CLOSED SYSTEM. Only insects eating plants parts are exposed to the product injected. In Eastern Canada, trunk injections have been used successfully to control Emerald Ash Borer, Asian Longhorn Beetle – two invasive species that kill large stands of trees.

This means that it is applied directly into the plant – no spraying, no mess, no rinsing. What is even better about this system is that it is:
