Product Q&A

Answer:

We do not recommend mixing Prime Source Quinclorac 75 DF Select Herbicide with a product such as TZone herbicide. Quinclorac requires the addition of an MSO surfactant, however you should not add a surfactant like that to TZone as this would likely damage your desirable turfgrass. 

We recommend applying a quinclorac product with the MSO surfactant as a separate application. Otherwise, you may consider using Q4 Plus Herbicide which has quinclorac plus some of the same active ingredients as TZone.
