  • Asked by John from Jeffersonville, Indiana 47130
    07/09/2021
    Q
    Is Q4 or Speed Zone best to mix with Tenacity and a surfactant as a general weed killer in late summer before
    I'm looking for a general weed killer that I can mix with Tenacity and a surfactant to spray my tall fescue lawn with in late summer 4-6 weeks before overseeing my lawn. Which is the best product for this?
    A
    Neither Q4 Plus Turf Herbicide nor Speedzone would be advised to tank mix with Tenacity.  Tenacity requires the use of a surfactant in post emergent spot treatment applications while the others do not, as Q4 already contains one and most Speedzone products list on the label to not mix as it can injure your turfgrass.  Depending on what you are treating for Q4 is the better option of the 3 for the most weeds.
