You could potentially mix SpeedZone Herbicide with a quinclorac product to broaden the spectrum of weed control. Something to keep in mind, though, is that most quinclorac products require the addition of a methylated seed oil (MSO) surfactant to help cut through the waxy coating on the target plants for best results. Adding this kind of 2-way surfactant with SpeedZone could increase sensitivity on your desirable turfgrass. We recommend first performing a small jar test for compatability, and then treating a small area with this tank mix for tolerance before mixing a large batch and/or treating the entire area.
No, it is not necessary to use a surfactant when applying SpeedZone Broadleaf Herbicide for Turf. Application instructions do not change and it actually says on the label that adding a surfactant could reduce the selectivity on the turfgrass. Please look at the label for application instructions.

No, Speedzone Red Herbicide is not labeled for use on Centipede or St. Augustine grass.
A better option would be Speedzone Southern. It is labeled for use on Centipede and St. Augustine grass and treats a lot of the same weeds that Speedzone Red does.
SpeedZone Red Herbicide cannot be used in pastures. Depending on what you are treating for you can use Martins Clear Pasture.
