Ox 240 EC, 10L (Herbicide)

OX 240 EC is a selective Herbicide with knockdown and residual soil activity used in New Zealand Horticulture and Forestry systems. It is designed to control Weeds in Orchards, Vineyards, Kiwifruit, Stonefruit, and Forest Nurseries, helping maintain clean ground conditions during early Crop establishment and the growing season. It works both on existing small Weeds and new germinating Weeds through soil activity.
Active Ingredient & Mode.
- Oxyfluorfen 240 g/L (EC formulation).
- Mode of action Group 14 Herbicide (PPO inhibitor).
What it Controls:
- Broadleaf Weeds + some Annual Grasses.
- Pre-emergence (before Weeds come up).
- Early Post-emergence (Seedlings ~4–6 leaf stage).
Typical Weeds Include:
- Ryegrass, Barley Grass.
- Amaranthus (Redshank).
- Blackberry Nightshade.
- Various Broadleaf Species.
Where It’s Used:
Approved Crops/situations include:
- Apples.
- Grapes.
- Kiwifruit.
- Stonefruit.
- Forestry Nurseries and Trees.
- Various Horticultural Crops.
Best used on bare soil or very small Weeds.
Residual Activity:
- Provides long residual control (up to ~6 months) in ideal conditions.
- Soil should not be disturbed after application.
Application Rates:
- Apply to clean, Weed-free soil, or small actively growing Weeds.
- For post-emergence add a non-ionic surfactant for better control.
Can be:
- Used alone or at low rates to boost knockdown Herbicides.
Typical Mix Rates: (per Hectare).
Orchards, Vines (Apples, Kiwifruit, Grapes, Stonefruit).
- Low rate (Maintenance / Clean Ground).
- 75–200 mL/ha.
- Standard Residual Control.
- 1–2 L/ha.
- Heavy Weed Pressure / Long Residual.
- 2–4 L/ha.
- Directed spray to base only.
- Higher rates only on established Trees (3+ years).
Forestry / Shelterbelts:
- 3–4 L/ha (typical).
- Up to 4 L/ha+ depending on species and timing.
Vegetables / Brassicas:
- 1.5–2 L/ha.
- Pre-plant / knockdown spike ~75 mL/ha (with Glyphosate or Paraquat mixes).
- Post-emergence (small Weeds) Usually Low rates (100–500 mL/ha) Often with Surfactant or in mix.
Water Rates: (important).
- Bare Ground: 250–500 L/ha, - Weeds Present: up to 1,350 L/ha for coverage.
Key Practical Points:
- Best results = bare soil or very small Weeds (≤4–6 leaf).
- Works by contact + residual barrier, Don’t cultivate after spraying, Avoid high rates on young Trees (Crop damage risk).
Simple Rule Of Thumb:
- Spike Mix: 75–150 mL/ha.
- General Orchard use: 1–2 L/ha.
- Long Residual / Heavy Weeds: 2–4 L/ha.
Major Safety & Hazard Points:
- This is not a low-risk product. “Too hazardous for use in the home garden”.
- Toxic to aquatic life and wildlife.
Can Cause:
- Eye irritation.
- Aspiration hazard (if swallowed).
- Long-term health risks with exposure.
Key Restrictions:
Do NOT:
- Spray near Waterways.
- Allow spray drift onto other Crops.
- Graze treated Weeds.
Use Care Around:
- Livestock.
- Sensitive Plants.
Withholding Periods:
- Grazing Do NOT graze treated Weeds.
- Harvest: Not required when used correctly.
Resistance Warning:
- Group 14 Herbicide → resistance can develop, Rotate with other modes of action to avoid failure.
Bottom Line.
- Strong residual Herbicide for Orchards & Forestry, Best on bare ground or very small Weeds, Long-lasting but strict safety controls required, Not suitable for Casual/Home use.
- Best tank mixes (e.g. with Glyphosate/Paraquat), or how it compares to products like Ethoken or Endow.
Caution:
Must be used strictly according to label directions.
