Henbit
Three-ways(2,4-D + MCPP + dicamba) alone do not control henbit. Effective control requires a tank mix of a postemergence herbicide with simazine or atrazine. Typical mixes are a three-way plus simazine or atrazine or metsulfuron plus simazine or atrazine. Apply early (between December and March 1) before the weeds get big.
