You will need to wash the product off while it is still wet to possibly prevent turf damage. If the product has already dried, it istoo late to stop the effects of the application. We recommend that you contact the manufacturer of SpeedZone Lawn Weed Killer Concentrate, PBI Gordon 800-821-7925. They are the experts on their product and can possibly help you with correcting this mistake.
