Note: In Canada, TreeAzin Systemic Insecticide is the only pesticide registered by Health Canada’s Pest Management Regulatory Agency. For emergency use only, TreeAzin Systemic Insecticide is for sale and use in Ontario and Quebec for management of emerald ash borer in ash trees until August 31, 2010. BioForest Technologies Inc. is seeking a full registration of TreeAzin Systemic Insecticide in Canada. In the United States, TreeAzin Systemic Insecticide is fully registed by the Environmental Protection Agency (EPA Registration Number 82996-1) and is listed by the Organic Materials Review Institute (ORMI).
Correction on Page 2: “TreeAzin (AI: Azadirachtin) Treatment Frequency: Once per year”
Research has shown that ash treated with TreeAzin receive up to two years protection against EAB. McKenzie et al. (2010) found the active ingredient, Azadirachtin had a significant effect on larval EAB development, and may negatively affect EAB populations through indirect reproductive effects on adults (i.e. sterilization). BioForest Technologies Inc. is recommending a treatment frequency of every two years with TreeAzin against EAB. A copy of McKenzie et al. (2010) may be found on our website.
