Product Q&A

Answer:

We would not recommend tank mixing the SpeedZone Lawn Weed Killer Concentrate 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 Speedzone.  Also you are required to use a surfactant with Tenacity for post emergent applications and EW does not require.  You can use Speedzone Speedzone the same day as Tenacity Herbicide for more broadleaf weed control.  Just allow areas to dry between treatments.
