For effective weed management in triticale, several herbicide options are available, designed for application at specific growth stages to ensure crop safety and efficacy. These herbicides target various weeds while being compatible with triticale.
The following table outlines common herbicide options suitable for triticale, along with their recommended application windows based on the crop's growth stage:
| Herbicide Name | Compatible Crops | Triticale Growth Stage for Application |
|---|---|---|
| Axiom | Wheat, Triticale | Spike-1 (2-leaf stage) |
| Clarity / dicamba | Wheat, Barley, Rye, Triticale, Oats | 3–6 leaf stage |
| Finesse Cereal and Fallow | Wheat, Barley, Triticale | Pre-emergent to 8 leaf stage |
| Harmony Extra / Express | Wheat, Barley, Triticale, Oats | 1–7 leaf stage |
Understanding Growth Stages for Application
Applying herbicides at the correct growth stage is critical for maximizing weed control and minimizing potential harm to the triticale crop. Each herbicide has a specific window during which it is most effective and safest for the plant.
- Pre-emergent to 8 leaf stage: This wide window, applicable for herbicides like Finesse Cereal and Fallow, means the product can be applied before the crop emerges or up to the point when the triticale has developed eight leaves.
- 1–7 leaf stage: Herbicides like Harmony Extra / Express are typically applied when the triticale plant has developed between one and seven leaves.
- 2-leaf stage (spike-1): Axiom is specific to a very early stage, when the triticale has just two leaves.
- 3–6 leaf stage: Products such as Clarity / dicamba are effective when triticale is within this intermediate leaf development range.
It is always important to consult product labels for specific instructions, rates, and any additional precautions before applying herbicides. For further detailed information on herbicide recommendations for winter small grains, including triticale, you can refer to resources like those provided by university extension services.
