What Are the Possible Treatments and Preventive Measures?

Protecting our trees is important and we must monitor their health carefully in order to preserve their wealth.

Preventive treatment
A treatment, called TreeAzin, helps fight the emerald ash borer. This treatment, safe for human health and for the environment, must be administered by a professional before the end of August. (You can view a list of professional arborists on the SIAQ website - in French only).

The municipality has been proceeding with this treatment by injection on ash trees on public territory since May 2014.

Financial Assistance Program for the treatment of Ash Trees in Dorval
In order to assist its citizens in the costs incurred for thetreatment of ash trees located on their property, the City of Dorval has established a financial assistance program. For details on this program, click here.

Tree removal
If, however, your ash is in an advanced state of decay * and that the only option remains to cut it down or remove it, certain security measures must be taken.

As such, ash trees must be pruned or cut only during a specified period, from October 1 to March 15.

This measure aims at reducing any chances of the emerald ash borer, in its adult stage, to fly and possibly spread, for it to be moved or carried around in infested cut pieces of wood, or for the insect to be attracted by freshly cut branches or stumps.

* An ash tree, which 30% of the branches are affected by dieback, is generally considered too infected to be saved by treatments.

Important reminder:

All tree removals require an appropriate certificate of authorization from the City of Dorval. (for more information on permits et certificates, click here).

To obtain a certificate, please contact the City’s Urban Planning Department at 514 633-4125.

For regulatory measures put forward by the Canadian Food Inspection Agency to counter the emerald ash borer spread, visit their website.
