banvine herbicide Cletho 240 EC 20L, (Vega) Herbicide (Controls Grasses) – SprayshopCletho 240 EC is a selective Post emergence Herbicide For the control of certain Grass Weeds in Beetroot, Cabbage, Canola, Celery, Chickpeas, Cotton, Faba Beans, Field Peas, Lentils, Lettuce, Lupins, Mung Beans, Non bearing Fruit Trees, Onions, Ornamentals, Peanuts, Potatoes and for Annual and Perennial Grass Control in Broadleaf Crops and Forestry. Active Ingredient: 240g litre Clethodim in the form of a Suspension Concentrate. What Is The Chemical:

Cletho® 240 EC is a selective Post-emergence Herbicide For the control of certain Grass Weeds in Beetroot, Cabbage, Canola, Celery, Chickpeas, Cotton, Faba Beans, Field Peas, Lentils, Lettuce, Lupins, Mung Beans, Non-bearing Fruit Trees, Onions, Ornamentals, Peanuts, Potatoes and for Annual and Perennial Grass Control in Broadleaf Crops and Forestry.
Active Ingredient:
240g/litre Clethodim in the form of a Suspension Concentrate.
What Is The Chemical:
- Group: Group 1 (ACCase inhibitor).
- Mode: Systemic Grass Herbicide.
- Same chemistry as Vega® — no difference in mode of action.
How To Apply:
- Adjuvant (NON-NEGOTIABLE).
- Must be mixed with Result® Spraying Oil.
- Rate 1L/100 L water / Max 2L/ha.
- If you skip Result® Spraying Oil → performance drops badly.(This is one of the most common real-world failures).
Timing (this makes or breaks it) The Best Timing Is:
- Young Grasses (2–5 leaf stage).
- Actively growing.
Avoid Spraying:
- Drought-stressed plants.
- Waterlogged plants.
- Recently grazed (without regrowth).
- Ideal let grass regrow to 5–10 cm fresh growth before spraying.
Rainfastness:
- Rainfast after 1 hour.
- That’s actually quite good compared to many Herbicides.
Rates: (very important — properly structured).
Light Grasses: (Easy Targets).
Rate 0.25 – 0.5 L/ha.
- Wild Oats.
- Ryegrass (Small).
- Barnyard Grass.
- Summer Grass.
Medium / Tougher Grasses:
Rate 0.5 – 1.0 L/ha.
- Barley Grass.
- Bromes.
- Tall Fescue.
- Poa.
Perennial / Hard Grasses:
Rate 2.0 – 3.0 L/ha.
- Couch.
- Paspalum.
- Indian Doab.
Reality Check:
- Established Turf Ryegrass → suppression only.
- Yorkshire Fog → suppression only.
- This is important in NZ — don’t expect miracles on old Pasture Grasses.
Crop Uses: (what you can actually spray).
- Legumes.
- Lucerne.
- Clover.
- Lotus, Trefoil.
- Strong fit here — very common use.
Brassicas: (Fodder Crops).
- Spray Early 3–6 weeks after planting before canopy closes.
- Can tank mix carefully (more below).
- Forage Herbs.
- Chicory.
- Plantain.
- Don’t spray Plantain once flower heads appear.
Vegetables: (Proven Safe On).
- Onions.
- Carrots.
- Lettuce .
Max Rate:
- 1 L/ha.
- Always test if unsure.
- Orchards directed spray only (avoid Fruit).
Forestry Radiata Pine, etc, Spot Spray 3.5 mL per litre.
Mixing Rules: (VERY important).
- Can Mix With:
- Some products like Timberwolf®, Ken-Trel® Herbicides.
Do NOT Mix:
With random Herbicides unless proven safe.
Within 7 days of Phenoxy Herbicides (e.g. MCPA®, 2,4-D®) "THIS IS CRITICAL" Mixing incorrectly = reduced Grass kill.
Application Setup:
- Water rate 100–300 L/ha.
- Droplet size 150–300 microns.
- Translation Medium spray quality (not too fine → avoid drift).
Withholding Periods:
- Vegetables → 5 weeks.
- Legumes / Forage / Brassicas → 3 weeks.
- Plan grazing accordingly.
Spray Hygiene:
- Clean out sulfonylurea residues before spraying.
After Spraying:
- Full detergent clean.
- Rinse twice.
- Residues from other chemicals can, damage Crops and reduce performance.
Resistance Management:
- Group 1 herbicide → high resistance risk.
The label explicitly warns:
- Resistant Ryegrass will survive and can dominate quickly, What this means in practice is.
- Do NOT rely on Cletho® 240 EC alone every season and rotate with other Herbicide groups and Grazing / Cultivation.
- NZ Reality Ryegrass resistance is already widespread.
Real-World Performance Warnings: (Based On Label).
- Old Pasture Grasses → often only suppressed.
- Dense infestations → need higher water rate and higher Chemical rate.
- Spray overlap → can damage Crop.
Key Mixing Insight:
Often better to Spray Cletho® 240 EC separately, Then Broadleaf Herbicide later, because mixing can reduce effectiveness.
Bottom Line:
- This is a standard, effective Clethodim® Product.
Works Best:
- Early timing.
- With Result® Spraying Oil.
- On Young Grasses.
Weak on:
- Old Pasture Grasses.
- Resistant Ryegrass.
Biggest Risk:
- Resistance buildup if overused.
Most Important Takeaways:
If You Remember Nothing Else:
- Always add Result® Spraying Oil.
- Spray young Grass (2–5 leaf).
- Don’t expect control on old Pasture.
- Don’t overuse (resistance risk).
Caution:
Must be used strictly according to label directions.
