For preemergence control, apply Specticle (indaziflam), Barricade (prodiamine), Pendulum(pendimethalin) and Dimension (dithiopyr) around March 1 or before crabgrass begins to germinate. For postemergence control, apply quinclorac (Quinclorac 75 DF,Drive, Drive XLR8) to tolerant turfgrasses when crabgrass is less than two tillers or mature. Repeat application in seven days. Use methylated seed oil for a surfactant.
