Since December 2011, more than 83,000 (and counting!) U-Haul customers have chosen to contribute to Tree Canada at time of renting a truck or trailer. These contributions support planting trees throughout Canada to help “Grow Clean Air’. In a recent project this summer, Tree Canada and U-Haul partnered to protect existing emerald ash trees in The City of Peterborough. In their native Asia, borers don’t cause much damage. However, in Ontario and Quebec, the insects have no natural predators. Their larvae are deadly to ash trees. They eat the trunks’ insides until nutrients can no longer reach the crowns, causing ash trees to die.
To combat the borer, an effective insecticide called TreeAzin is administered by drilling holes in the tree trunk and injecting the liquid with large syringes. Injections of TreeAzin help prevent infestations of the emerald ash borer, ensuring these trees grow and enrich the urban forest of The City of Peterborough. TreeAzin is the only pesticide used for this initiative as it is an effective natural product with very low environmental toxicity.
