Dismiss Turf Herbicide does state on the product label that it is believed to be compatible with most herbicides commonly used in turf and ornamental plant management. However, when preparing a new tank mix conduct an appropriate compatibility test by following the instructions on the label. Though the SpeedZone Southern product label states: Do not use tank mixture combinations, unless your experience indicates that the tank mixture will not result in turf injury.
