Effective on killing and controlling horsetail (marestail)

Kurtail Gold is based on glufosinate ammonium, so users of Kurtail & Kibosh can be assured of the same high level results. 

PLUS NEW Kurtail Gold is now even more versatile - with a wider range of uses: -

Application notes and guidance:

  • Horsetail is often called mare's tail but this is more accurately an aquatic weed (hippuris vulgaris). The correct latin name for horsetail is Equisetum arvense or ‘field horsetail’.NB:  Kurtail Gold is not approved for aquatic use.
  • Its root system is extremely vigorous and can grow very deep which is why it can regenerate after treatment and cultural controls, such as digging or rotorvating, will only spread and multiply the problem in the short term. Please phone us if you intend to build over treated areas...eg, tarmac drives
  • It is preferable to allow the horsetail / mares tail weed to wither and die naturally before cutting or removing the weed. If this is not possible, then a minimum of 3 weeks should elapse before cutting or removing. Any horsetail/mares tail roots which emerge after treatment will require respraying.
  • Spraying of mare's tail should not take place if rainfall is due within 8 hours (minimum), 24 hours is preferable for best results.
  • Please read the label before use.
  • Please note that more than one application may be required, as new growth can emerge after the initial application.
