SureFire Treeson Herbicide 500mL: Woody Weed & Unwanted Tree Control

SureFire Treeson Herbicide 500mL is a professional-strength herbicide for controlling unwanted trees and hard-to-kill woody weeds. It contains two active constituents, triclopyr at 200 g/L and picloram at 100 g/L, which move deep into the plant to kill it at the root and help prevent regrowth. It's a Group I herbicide, comparable to Tordon Double Strength, and is well suited to forestry, pasture, rights of way, and commercial, industrial and non-crop areas across Australia.

Treeson is an aqueous concentrate that mixes with water, not diesel, which makes it a practical option where oil-based ester formulations are restricted. Applied through targeted techniques, it gives strong control of single and multi-stemmed saplings while keeping off-target risk low.

Target Weeds & Trees

Treeson is registered to control unwanted timber by stem injection or cut stump, and blackberry, gorse and harrisia cactus by foliar spray. Target species include acacia/wattle, angophora, camphor laurel, casuarina/sheoak, corymbia, eucalyptus, melaleuca and lophostemon, along with blackberry, gorse and harrisia cactus. Always check the label for species-specific directions and exceptions.

How to Use

Treeson is applied by stem injection, cut stump or foliar spray, and is mixed with water according to the label:

• Stem injection: Mix 1 part Treeson with 4 parts water. Ideal for mature trees. Make cuts and apply immediately so the herbicide is drawn into the sap stream before the cut seals.
• Cut stump / brushcutter: Mix 500mL per 10L of water. Suited to saplings too small to stem inject. Apply to freshly cut stumps straight away to help stop regrowth.
• High-volume foliar spray: Mix 500mL to 2.5L per 100L of water, depending on the species and density. Spray to thorough coverage, targeting the crown, runners and tips.

A surfactant isn't needed for cut stump work, but is recommended for foliar spraying. Always read the label for the correct rate for your target species and situation.

Safety

Treeson is a scheduled poison. Keep it out of reach of children and pets, wear protective clothing, gloves and eyewear, and avoid spray drift onto sensitive plants or water bodies. Don't apply to stressed or non-growing weeds. Store in a cool, well-ventilated place and follow all label directions and safety instructions.

FAQS

What is the active ingredient in SureFire Treeson Herbicide?
It contains two actives: triclopyr at 200 g/L and picloram at 100 g/L. It's a Group I herbicide.

What is the mixing ratio for Treeson?
It depends on the method. For stem injection, mix 1 part Treeson with 4 parts water. For cut stump or brushcutter use, mix 500mL per 10L of water. For high-volume foliar spraying, mix 500mL to 2.5L per 100L of water. Always follow the label rate for your target species.

Do I mix Treeson with water or diesel?
Water. Treeson is an aqueous concentrate designed to be mixed with water, which is one of its advantages where oil-based ester products are restricted. It is not a basal bark diesel product.

What weeds and trees does Treeson control?
Unwanted timber such as wattle, angophora, camphor laurel, casuarina, corymbia, eucalyptus, melaleuca and lophostemon, plus blackberry, gorse and harrisia cactus. Check the label for exceptions and approved use situations.

How do I use Treeson for cut stump treatment?
Cut the stump, then apply the mixed solution, 500mL per 10L water, to the fresh cut surface straight away before it seals. This helps prevent the tree regrowing after cutting.

How long does Treeson take to work?
Woody weed control is often slow, and it can take several weeks for symptoms to show and months for a full kill. Avoid cutting or burning treated plants too early, as this can trigger regrowth.

Is SureFire Treeson available with free shipping?
Yes. BPG Supplies ships Treeson with free delivery Australia-wide. Note that as a dangerous good it travels by courier, so a courier-accessible address is required.
