Differences between emamectin benzoate products and tree injection systems esed to control emerald ash borer

While several insecticide active ingredients provide control for emerald ash borer (Agrilus planipennis), emamectin benzoate (EB) provides extremely effective control for more than one year and can be applied directly into the tree using an injection system. While this active ingredient is the favored product among urban forest managers, insecticide trials comparing the different formulations and new tree injection systems on the market are limited. This has left a gap in the data urban foresters need to select the most fitting product, method of application, and treatment cycle for their communities. To investigate the differences between liquid formulations of EB products labeled for use on emerald ash borer, we compared the insecticide labels, searched relevant literature, initiated discussions with chemical company representatives, and sent a questionnaire to industry professionals (including arborists, urban foresters, and researchers). This presentation compiles information on the different EB products and reports the conclusions, it is not intended to endorse any product.
