We would not recommend tank mixing the Speedzone EW Broadleaf Herbicide for Turf and Tenacity if you are using as a post emergent, only if you are applying as a pre-emergent application. With Tenacity you are only spot treating weeds directly that are actively growing, you would not broadcast as you can with the EW. Also you are required to use a surfactant with Tenacity for post emergent applications and EW does not require. You can use Speedzone EW the same day as Tenacity Herbicide. Just allow areas to dry between treatments.
It is not required to add a surfactant/adjuvant Speedzone EW Broadleaf Herbicide for Turf per the product label as doing so could injure your lawn. Clover is very hard to kill and is best treated when it just emerges. Once it flowers it is almost impossible to control. Triclopyr is an option for tank mixing with another herbicide following a jar test to ensure compatibility.
While its possible the Speedzone EW Broadleaf Herbicide for Turf could do some kill on the new sprouts coming off of a Sweet Gum Tree stump, you would be better off using a stump killer product. Fertilome Brush & Stump Killer is a great option to paint undiluted onto the freshly cut surfaces of the stump and sprouts you have snipped with a brush. This will help to provide kill to the stump and sprouts without impacting surrounding vegetation. If you find that the suckers continue to come back, you may need to remove the entire stump itself, or use something like Hi Yield Stump Remover to try and degrade and speed up the break down process of the existing stump.

Speedzone EW Broadleaf Herbicide for Turf is a white opaque liquid concentrate that is diluted with water for applications as directed on the label.
We do not recommend mixing those products together due to the surfactant concern. Quinclorac 75 DF requires the addition of an MSO surfactant for best results, but if you added that kind of surfactant to the Speedzone EW Broadleaf Herbicide for Turf, then you are more likely to damage your desirable grass. Q4 would be a better option as no additional surfactant is required and it targets more broadleaf weeds as well as containing quinclorac.
