Description
How does Tebulex 200GR Herbicide work?
Tebulex 200GR Herbicide contains tebuthiuron, a non-selective urea-group herbicide. Once applied to the soil, it is absorbed through a plant’s root zone, where it travels into its foliage. Tebuthiuron then inhibits photosynthesis, stopping the plant from converting sunlight into the energy it needs to thrive. This leads to repeated defoliation and eventually, total plant death.
When should Tebulex be applied for best results?
Thanks to its granular formulation, Tebulex 200GR can be applied at any time throughout the year. After application, rainfall activates the pellets, moving the active ingredient through the soil and into the plant.
Control develops over time, with woody weeds often cycling through regrowth and defoliation phases before dying off completely. Residual activity in the soil can last for several years, with results varying based on rainfall, soil type, weed species, and application rates.
Which weed species is Tebulex Herbicide registered to control?
Tebulex 200GR is APVMA-registered for use on a number of weed species commonly found in Australia, including:
| African boxthorn (Lycium ferocissimum) | Dawson gum (Eucalyptus cambageana) | Pink bloodwood (Corymbia intermedia) |
| Belah (Casuarina cristata) | False sandalwood (Eremophila mitchellii) | Poplar box (Eucalyptus populnea) |
| Black tea-tree (Melaleuca bracteata) | Gidgee (Acacia cambagei) | Poplar gum (Eucalyptus platyphylla) |
| Blue heliotrope (Heliotropium amplexicaule)# | Groundsel bush (Baccharis halimifolia) | Prickly acacia (Vachellia nilotica) |
| Brigalow (Acacia harpophylla) | Gum-topped box (Eucalyptus moluccana) | Rubber vine (Cryptostegia grandiflora) |
| Broadleaf ironbark (Eucalyptus fibrosa) | Holly bush (Alchornea ilicifolia) | Scrub boonaree (Alectryon diversifolius) |
| Broadleaf tea-tree (Melaleuca viridiflora) | Lantana (Lantana camara)* | Swamp box (Lophostemon suaveolens) |
| Brown box (Eucalyptus brownii) | Limebush (Citrus glauca) | Whitewood (Atalaya hemiglauca) |
| Cocky apple (Planchonia careya)* | Mimosa pigra (Mimosa pigra) | Wild rosemary (Eriocephalus africanus) |
| Coolibah (Eucalyptus coolabah) | Paperback tea-tree (Melaleuca quinquenervia) | Yellowwood (Flindersia xanthoxyla) |
| Currant bush (Carissa ovata and Carissa lanceolata) | Parkinsonia (Parkinsonia aculeata) |
* Some suppression is provided at the rates given.
# Do not use within 30 m of trees.
Why select a tebuthiuron-based herbicide?
Tebuthiuron-based herbicides like Tebulex are well-suited to a range of contexts, such as:
- Graziers managing brigalow and tea tree regrowth
- Landholders dealing with persistent woody weeds
- Large-scale properties requiring low-labour, long-acting residual control
- Areas where follow-up spraying is impractical or costly
Considerations when using Tebulex 200GR Herbicide
Though Tebulex is extremely effective and suited to a variety of contexts, there are a few things users should know before administering this herbicide to kill woody weeds.
- Gradual effect: Tebulex is not a knockdown herbicide, but rather, moves gradually through the plant’s root system, resulting in long-term control rather than rapid burnoff.
- Residual damage: The rates required to eradicate woody weeds may temporarily suppress or kill nearby grasses. To minimise negative impacts, apply Tebulex 200GR when grasses are dormant.
- Environmental factors: Overall pasture response to tebuthiuron will depend on rainfall and the grazing management strategies in place.
- Directions for use: Always adhere to label directions, including specific advice for the soil type and target species, to ensure best results and safe application.
Frequently asked questions
How long does Tebulex 200GR last in the soil?
Tebulex’s residual control can persist for up to several years after application, depending on factors like soil type, rainfall, application rate, and target species.
Does Tebulex kill grass?
Tebulex is deemed selective on most grasses, but may cause temporary herbicidal symptoms in perennial grasses. When applied at a higher application rate, Tebulex may kill grasses, particularly native annuals. To reduce impact, consider administering the herbicide while grasses are dormant.
Is Tebulex fast-acting?
No. Tebulex is slow-acting by design, providing long-term control rather than immediate knockdown results.
Can Tebulex be applied aerially?
Yes. Tebulex 200GR is suitable for aerial, ground, and hand application, making it an ideal choice for large or inaccessible areas.
