Horehound trial locations

To demonstrate herbicide(s) and timing of application options for the control of horehound.

Key messages
  • Treat infested pastoral areas with 3.0 litres MCPA amine per hectare in the autumn. Apply the MCPA with 100 litres of water per hectare. Horehound can be a difficult plant to wet. A wetting adjuvant may be of assistance.
  • Maintain grasses to prevent the establishment of seedlings. Burn the infested area the following year, in early
  • autumn, to destroy as much of the seed bank as possible. Respray the area later in the autumn to control any subsequent horehound germinations with MCPA amine.
