Plain Language Summary

This technical note outlines the development and registration of TreeAzin® for use against the emerald ash borer (EAB). This invasive alien insect pest is killing ash trees across North America. Municipalities have spent millions of dollars removing and replacing affected ash trees. Canadian Forest Service scientists have developed a natural insecticide based on extracts from the neem tree. They partnered with BioForest Technologies to develop a suitable formulation of the compound and an application system. TreeAzin® is injected directly into the base of a tree because the beetle feeds under the bark. This control method is suitable for protecting high value ash trees that have not been extensively damaged. In October 2012, TreeAzin® was granted national registration by the Pest Management Regulatory Agency. This research aligns with the government’s mandate to protect Canada’s natural resources from disturbances such as forest invasive alien species.
