The City of Sherbrooke has granted a two-year contract to the company Strathmore Landscaping to fight emerald ash borer infestation with TreeAzin, a systemic insecticide. This contract will allow ash tree owners to access treatment at a lower cost. Ash trees owners wishing to use the group price will have to go to the website sherbrooke.ca/agrile and fill out the form found on the homepage under the button ‘Traiter votre frêne’. The cost for treatment will be $3.49 per centimeter of the tree’s diameter, which will be measured 1.2 m from the ground. The minimum diameter is set at 20 cm. or about 8 inches.Treatment must take place between June 15 and August 31, with the ideal being to treat early in the season. Residents can also go to their borough office to request treatment if they do not have internet access. The city is also reminding residents that treatment is most effective when trees are only slightly or not affected at all. TreeAzin treatment should be repeated every two years. In cases of severe infestation, it may be appropriate to treat two years in a row at certain times. See full story in the Wednesday, March 21st edition of The Record.
