Field Madder, Sherardia arvensis
Sherardia arvensis
Glyphosate alone does not control field madder. Effective field madder control requires a tank mix of a postemergence herbicide with simazine or atrazine. Typical mixes are a three-way plus simazine or atrazine or Manor or Blade plus simazine or atrazine. Apply early (between December and March 1) before the weeds get big.
