Solstar 10L (Herbicide)

Solstar® is a selective Herbicide for the control of Broadleaf Weeds in Cereals and Apples. It gives rapid knockdown and improved control of difficult-to-control Broadleaf Weeds – including White Clover, Docks, Mallow and Black Nightshade.
Active Ingredient:
200 g/L Fluroxpyr as the Methylheptyl Ester in the form of an Emuslifiable Concentrate.
Where It’s Used:
Cereals:
- Wheat.
- Barley.
- Oats.
- Orchards (e.g. Apples) directed sprays under Trees.
Important:
- Avoid contact with crop foliage/bark in Orchards.
- Do not use in undersown crops (e.g. Clover/Lucerne).
What It Controls:
Strong on Broadleaf Weeds, including:
- White Clover.
- Docks.
- Mallow.
- Black Nightshade.
- Chickweed.
- Cleavers.
- Wireweed.
- Particularly good on hard-to-kill Broadleaf Weeds.
How It Works:
- Systemic herbicide (absorbed through leaves).
- Mimics plant growth hormones (auxin effect).
Causes:
- Uncontrolled growth.
- Plant death.
Key feature:
- Fast knockdown compared to many selective Herbicides.
Application Guidance: (General Spraying)
Water Rate:
- 100–200 L/ha (standard).
- Up to 300 L/ha for later/denser crops.
Timing:
- From 3-leaf stage → flag leaf (booting) in Cereals.
Rainfast:
- Avoid spraying if rain expected within 2 hours.
Mixing & Tank Partners: (Important Strength).
Solstar® is commonly used in tank mixes:
- With Glyphosate® → improved knockdown in non-crop/burn-down use.
- With MCPA® / 2,4-D® / Clopyralid® → broader weed spectrum.
Example: (From Label).
- Docks Solstar® + Glyphosate® + Penetrant.
Key Limitations:
- No grass weed control.
- Less effective on large or mature weeds.
- Can damage sensitive crops via drift.
- Works best on small, actively growing weeds.
Crop Safety & Drift Warning: (Critical).
- Spray drift can cause serious damage to nearby plants.
Avoid:
- Windy conditions.
- Spraying near sensitive crops.
Withholding Period:
Cereals:
- Do not graze failed crops for 7 days.
Apples:
- Do not harvest within 28 days.
Safety & Environmental Hazards:
Causes:
- Eye irritation.
- Mild skin irritation.
- Very toxic to aquatic life & soil organisms.
Precautions:
- Avoid waterways.
- Wear PPE.
- Clean equipment thoroughly.
Resistance Management:
- Group 3 Herbicide.
- Resistance risk exists (especially with repeated auxin use).
Best Practice:
- Rotate with other Herbicide groups.
- Use in mixtures where appropriate.
- Simple way to think about it.
- Solstar® = “selective broadleaf cleaner” in Cereals.
Stronger than many older options on:
- Clover.
- Docks.
- Nightshade.
Often Used:
- Alone for selective spraying or in mixes to boost weed spectrum.
Bottom Line:
- Solstar = fast, selective Broadleaf Herbicide.
Best Used:
- In Cereals.
- On young, actively growing Weeds.
Big Strengths:
- Fast knockdown.
- Mix flexibility.
Main Risk:
- Spray drift damage.
Caution:
Must be used strictly according to label directions.
