Linuron Flo 450 SC Herbicide 10L (Afalon)

Linuron Flo 450 SC is for the control of weeds in Carrots, Parsnips, Asparagus, Onions, Maize, Sweetcorn, Linseed, Celery, Leeks, Pipfruit, Stonefruit and Grapes.
Active ingredient:
400g/litre Linuron SC
Controls mainly:
Broadleaf Weeds.
- Fathen.
- Nightshade.
- Chickweed.
- Some Annual Grasses.
Used in:
- Carrots.
- Onions.
- Potatoes.
- Maize.
- Sweetcorn.
- Asparagus, etc.
Mixing Rates per Tank (Field Examples)
~ Typical label rates vary by crop, but generally 1.0 – 2.0 L/ha (most situations).
- Example: 200L Tank.
~ Scenario A: 200 L/ha (1 tank = 1 ha).
Rate: 1.5 L/ha Add 1.5 L per 200L tank.
~ Scenario B: 100 L/ha (tank covers 2 ha).
Rate: 1.5 L/ha Add 3.0 L per 200L tank.
~ Scenario C: Light soils / lighter weed pressure.
Rate: 1.0 L/ha 200 L/ha → 1.0 L per tank.
~ Quick Rule Tank rate = (ha per tank) × (L/ha rate).
Mixing Tips(Important with Linuron)
- Keep constant agitation (SC formulation settles).
- Add early in tank (unlike insecticides).
- Works best with even soil coverage.
- Needs moisture (rain/irrigation) to activate.
Best Alternatives / Rotation Partners.
- Linuron = Group 5 (PSII inhibitor) → resistance risk if overused.
Good Rotation Options:
- Group 15 (Residual grass + broadleaf) S-metolachlor (e.g. Dual-type products).
~ Strong partner in maize/sweetcorn.
- Group 27 (HPPD inhibitors) Mesotrione.
~ Excellent on fathen & broadleaf weeds.
- Group 3 (Dinitroanilines) Trifluralin / pendimethalin.
~ Pre-emergence grass + some broadleaf.
- Group 9 (Non-selective) Glyphosate (burn-down before crop).
~ Clean start before linuron residual.
~ Simple Rotation Strategy.
- Don’t stack Group 5 repeatedly.
Example:
- Pre: Glyphosate.
- Residual: Linuron.
- Follow-up: Mesotrione.
Suitability by Crop (Very Practical)
~ Carrots / Parsnips.
- Excellent fit One of the main linuron crops.
Controls:
- Fathen.
- Nightshade.
- Chickweed.
Often used:
- Pre-emergence.
- Early post (careful timing).
~ Onions / Leeks.
- Very common use Good on Small broadleaf weeds.
Crop Sensitivity:
- Timing is critical (small onions easily damaged).
~ Potatoes.
- Good fit Used pre-emergence or early post.
Controls:
- Nightshade.
- Early broadleaf weeds.
~ Often mixed with Metribuzin or other residuals.
~ Maize / Sweetcorn Moderate use Helps control Early broadleaf weeds.
~ Usually NOT enough alone.
~ Best used In combination with S-metolachlor Mesotrione.
~ Asparagus.
- Very useful Strong residual control Fits well in perennial systems.
~ Pipfruit / Stonefruit.
- Niche use Strip spraying under trees Residual weed control.
Key Practical - Takeaways.
~ Strengths Strong residual control Good on fathen + nightshade Widely trusted in veg crops.
~ Weaknesses Needs soil moisture to activate.
- Weak on, Large Weeds, Some Grasses, Resistance risk if overused.
~ When to Use Linuron.
- Pre-emergence or very early post When you want residual control In Carrots, Onions, Potatoes.
~ When NOT to Rely on It Alone.
- Heavy grass pressure.
- Large established weeds.
- Dry conditions (won’t activate well).
~ Simple Practical Program Example (Maize).
- Pre-plant: Glyphosate.
- Pre-emerge: Linuron + S-metolachlor.
- Post: Mesotrione.
~ Covers both grass + broadleaf + resistance.
Caution:
Must be used strictly according to label directions.
