October - Fathen

FathenFathen (Chenopodium album)

Fathen is very common throughout New Zealand but is especially abundant in arable districts. Growing mainly in spring and summer, this erect weed can grow up to 2m tall. It is known as a very competitive weed due to its ability to remove moisture from the soil even in dry conditions. The grey-green leaves are up to 7cm long, sword shaped and have margins that appear toothed. Main stems and laterals often have green, yellowish or sometimes reddish ribs and can become quite hardy. Fathen normally forms very small green flowers between December and May that develop into a tight cluster of seeds up to 30cm long. Seeds remain viable in the soil for long periods of time.

Some people eat fathen as it is very palatable and nutritious.

  • New Pasture:
    Fathen is a common weed in young (new) pasture. Select* and MCPB * Herbicides provide excellent control of fathen without damaging either pasture grasses or clovers.
    Select – 4L/ha (seedlings)
    MCPB – 4L/ha (seedlings)
  • Established Pasture:
    Pasture-Kleen* and MCPA can be applied to larger and actively growing plants if growing in established pasture. These two herbicides cause temporary suppression of clovers.
  • Spot Spraying:
    Spot spraying in established pasture can be undertaken with Tordon* Gold. This herbicide is grass friendly but will temporarily remove clovers from the sward.
  • Fodder Brassica:
    In fodder brassica crops, Radiate* herbicide provides excellent control of this thirsty, yield suppressing weed without damaging your crop.
