As long as both products do not contain the same active ingredient, and both have labels that allow tank mixing in general then you should be able to. Per the Drive label: The most restrictive labeling applies with any tank mix. To increase spectrum of control of broadleaf and other weeds, Drive XLR8 may be tank mixed with 2,4-D, Triclopyr, and other broadleaf herbicides. Make sure to do a tank mix test first for any clumping or discoloring before applying to the lawn. Please note: Drive XLR8 requires the use of a methylated seed oil surfactant for best results. Since most broadleaf weeds killers do not require the use of a surfactant and the use of a surfactant can reduce selectivity on tolerant turfgrasses causing injury to the lawn. If tank mixing, we recommend doing a small test spot spray application to target weeds to test for any discoloration or injury before broadcasting over the entire lawn area.
