Hairy Bittercress, Cardamine hirsuta
Cardamine hirsuta
The dinitroaniline (prodiamine, pendimethalin, others) herbicides do not provide effective preemergence control of hairy bittercress. Effective hairy bittercress 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.
