Is Merit 2F Insecticide good for a soil injection to protect from emerald ash borers?
Merit 2F Insecticide is an excellent choice for a soil injection systemic control for emerald ash borers. Please refer to the product label prior to application for complete usage instructions. You will need to have measurements of the trees diameter or the shrubs height to determine how much product you will need to apply. Please let us know if you need anything else.
