Active Ingredient:
100 g/L Picloram, and 8g/L Aminopyralid as the Amine Salt and 300 g/L Triclopyr as the Butoxyethyl Ester in the form of a Emulsifiable Concentrate.
What It Controls:
The Label Highlights Control Of Brushweeds:
- Blackberry.
- Gorse.
- Broom.
- Broadleaf Weeds in Pasture.
Also Commonly Used On:
- Thistles.
- Dandelion.
- Clover (will be suppressed/removed).
This is much stronger than standard Pasture sprays and is designed for hard-to-kill Weeds.
Where You Can Use it: (Approved Uses Include).
- Pasture (Grass dominant).
- Forestry.
- Non-crop areas.
- Amenity/Turf situations.
Important:
- Will damage or kill desirable Broadleaf Plants.
Not Suitable For:
- Gardens.
- Vegetables.
- Sensitive Crops.
How it Works:
Systemic Herbicide (moves through the Plant) Mimics Plant Hormones → uncontrolled growth → death. Because it’s Systemic it works well on deep-rooted and Woody Weeds.
Mixing & Application: (Practical Interpretation).
- Exact rates vary depending on Weed type, but label-style guidance.
Spot Spraying: (Knapsack).
Typically 10–20 mL per litre for general Weeds Higher rates for Woody Weeds like Gorse and Blackberry.
Boom Spraying:
- Roughly 1–6 L per Hectare depending on target Weeds.
Key idea:
- Light Weeds → lower rate.
- Woody/established Weeds → higher rate.
When To Spray: (CRITICAL).
Best Timing:
When Weeds are actively growing and there is good leaf area for uptake.
For Brushweeds:
- Spray during spring to autumn growth periods.
Avoid:
- Drought stress.
- Frost.
- Extreme heat.
Residual Activity: (IMPORTANT).
- Because of Picloram & Aminopyralid this product has soil residual activity and can stay active in soil for months.
Can Affect:
- New plantings.
- Sensitive Crops later.
- This is a major difference from products like glyphosate.
Spray Drift Warning:
- High-risk product for off-target damage.
Can Drift And Damage:
- Trees.
- Crops.
- Gardens.
- Hormone Herbicides are especially prone to drift damage.
Always:
- Spray in low wind.
- Use coarse droplets.
- Avoid temperature inversions.
Safety & Hazards: (From SDS).
- Harmful if swallowed.
- Causes skin irritation/allergic reaction.
- Causes eye irritation.
- May cause organ damage with long exposure.
- Very toxic to aquatic life.
PPE Required:
- Gloves.
- Protective Clothing.
- Eye/face Protection.
Environmental Risks:
Highly Toxic To:
- Waterways.
- Soil organisms.
- Wildlife.
Label Implications:
- Keep away from Drains and Streams.
- Prevent runoff.
Key Use Strengths:
Excellent For:
- Gorse Control.
- Blackberry Control.
- Woody Brush Cleanup.
- Long-term Pasture Weed Control.
Often Used Where:
- Standard Herbicides fail.
Key Mistakes To Avoid:
- Using near sensitive Plants.
- Residual + drift = long-term damage.
- Expecting quick burn-down.
- Works systemically → takes time.
- Using too low a rate on Woody Weeds leads to regrowth.
- Replanting too soon.
- Residual Herbicide can kill new Plants.
Bottom Line:
- Powerful selective Brushweed Herbicide.
- Works on tough, Woody, deep-rooted Weeds.
- Grass-safe (generally) but kills most Broadleaf Plants.
- Has long soil residual.
- Requires careful handling and placement.
Caution:
