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.
