Can SpeedZone Lawn Weed Killer Concentrate be sprayed on St.Augustine?

I see that the label of SpeedZone Southern Herbicide EW is labeled for St. Augustine, but what about the ready to use formula?

Answer:

SpeedZone Lawn Weed Killer Concentrate needs to be diluted with water. This product is not for use on St. Augustinegrass. SpeedZone Southern Herbicide EW may be used on St. Augustinegrass. Please review the product label for prohibitions of sites and further information about applications.
