I have a 30 gallon tank to spray for pre and post emerging weeds in May.
Q4 Plus Turf Herbicide should be fine to mix with a pre-emergent such as Dimension 2EW as long as both labeled rates are followed for application. We would recommend doing a tank mix compatibility test first to make sure there is no clumping when mixing the two products together.
