Turfgrass Weed Control Database
The Turfgrass Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-521. The weeds are arranged alphabetically by scientific name because common names vary and thus be inaccurate.
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.
