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:
450 g/litre LINURON in the form of a suspension concentrate.
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 generally1.0 – 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 Flo 450 SC)
– 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 Flo 450 SC = 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 Flo 450 SC residual.
~ Simple Rotation Strategy.
– Don’t stack Group 5 repeatedly.
Example:
– Pre: Glyphosate.
– Residual: Linuron Flo 450 SC.
– Follow-up: Mesotrione.
Suitability By Crop (Very Practical)
~ Carrots / Parsnips.
– Excellent fit One of the main Linuron Flo 450 SC 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 controlEarly Broadleaf Weeds.
~ Usually NOT enough alone.
~ Best used In combination withS-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 Flo 450 SC.
– 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.
