To perform a soil drench on trees you should apply 0.1 to 0.2 fl. oz. (3 to 6 mL) of ImidaPro 2SC per inch of trunk diameter. Apply no less than 10 gallons of water per 1,000 square feet as a drench around the base of the tree, directed to the root zone. Any plastic or other barrier that may prevent drench solution from reaching the root zone must be removed.
