Yes, the Permethrin SFR 36.8% may be used with a turf marker/dye. Add a small amount of the Turf Mark Blue to any liquid insecticide concentrate, herbicide or fungicide and see exactly where you've sprayed. Turf Mark Blue is mixed at a rate of 1/2 - 1 oz. of concentrate per 1 to 3 gallons of liquid insecticide. When applied to turf, the dye disappears within 24-48 hours. Do not use for general pest control treatments around a home as the product will stain and can be difficult to remove.
