In this case, because Drive XLR8 Herbicide Crabgrass Killer requires the use of an MSO Surfactant like Prime Source Duo Stick Select in order to be effective, it would not be recommended due to the fact that most Turflon Ester product labels advise not adding a surfactant for lawn treatments as this can cause damage to turf grass.

It can take drive up to 6 weeks to completely kill.
