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.
Lawn Burweed, Soliva sessilis
Simazine or atrazine will provide pre and postemergence control of spurweed if applied early. For best results apply between Thanksgiving and Christmas. If that timing is missed make the application before March 1. Metsulfuron (Manor, Mansion or Blade) or three-ways (MCPP + dicamba + 2,4-D) provide postemergence control of spurweed. Metsulfuron or a three-way may be tank mixed with either simazine or atrazine.
