How It Works:
- Absorbed through Leaves, Stems, Roots.

Best Results:
- Good moisture.
- Warm conditions.
Poor Results:

- Avoid spraying if drift likely.
Typical Rates: (General Guide).
From Label Examples:
- Clover: ~0.7 L/ha.
- Thistles / Yarrow: ~1 L/ha.
- Tough Weeds (Ragwort etc) up to 2 L/ha.
- Spot spraying ~100 mL per 100 L water (varies by Weed).
- Forestry & Heavy Weeds Can be used at very high rates (10–25 L/ha) for Woody Weeds.
- Often mixed with other Herbicides.
- May cause temporary tree distortion.
Resistance Management:
- Repeated use → resistant Weeds possible.
- Rotate with other Herbicide Groups.

- Not suitable for casual/home use.
Caution:
Must be used strictly according to label directions.
