| Australian sedge (Carex longebrachiata) |
| Family: Cyperaceae |
| Description: |
|
Australian sedge is a tussock-forming, perennial sedge, up to 90
centimetres tall. It has long, drooping, narrow cutty leaves and
seed heads. |
| Other names: |
| Bergalia tussock. |
| Values at risk: |
| Agricultural production, particularly on hilly pastures. Ecological values, through the suppression of native plants and seedlings along scrub and forest margins. |
| Strategy rule: |
|
You must destroy all Australian sedge on your property within 25 metres of your boundary. |
| How to destroy: |
| Pasture management. Australian sedge spreads
most rapidly on areas exposed by low soil fertility, overgrazing,
insect damage or dry conditions. The best protection against re-infestation
from seed lying in the soil is a dense pasture cover.
Grubbing or digging out Australian sedge should be used only to deal with scattered smaller plants. For heavier infestations or larger plants, grubbing tends to be ineffectual. The break-up of the sward and the ground disturbance tends to encourage seeds to germinate, and the ground to become re-infested with seedlings. Using a herbicide such as glyphosphate may be effective on young or old plants. NOTE: Following both grubbing and spraying, seedling regrowth can occur for several years afterwards, so follow-up treatment is VERY important. |
