  • Multiple Application Methods: Highly versatile; it can be applied via stem injection, cut stump, basal bark, frill application, or foliar spray.
  • Selective Systemic Action: It is absorbed through leaves, stems, and roots, moving through the plant's vascular system to ensure complete kill of the entire specimen.
  • Rainfastness: Becomes rainfast within 2 hours of application once the spray has dried.

Application Rate

  • 500 ml to 2.5L of herbicide per 10L of Water

MIXING
Mix only with water. It will not mix with oil or diesel fuel. Only mix sufficient solution for immediate daily use and avoid storing.
A Stem Injection Application
Mix one part Surefire TREESON Herbicide with 4 parts clean water. Agitate well before commencing work. After use, clean equipment thoroughly and rinse several times with water.
B High VolUme Application
Half fill the spray unit with water, and add the required amount of Surefire TREESON Herbicide. Add the remaining water with the agitator running. If required, then add spray oils or wetters (surfactants).
Maintain mechanical or by-pass agitation in the spray tank during spraying.


APPLICATION
A Stem Injection Application
Waist Height Application
• To make an injection pocket at waist height, use a % length axe with a blade width of 5 to 7cm. The cut of injection must be through the bark and deep enough to place all the chemical in contact with the sap wood.
• The chemical must be applied immediately after the dose pocket is made. Apply chemical with a Phillips 5 mL vaccinator fitted with a tree injector kit which can be accurately calibrated. Set vaccinator to deliver 1 mL of herbicide mix.
• When treating regrowth less than the width of the axe, ensure chemical does not run out the sides of the cut, as reduced control will result. This can be overcome by using the corner of the axe to make the pocket in the stem or treating by cut stump application.


GROUND LEVEL APPLICATION
• To make an injection pocket at ground level, use a narrow blade axe, as described for waist height application, or a C.M.B. Engineering Tree Injector designed for this application method.
• When using the Tree Injector, make sure that the pump handle is held in whilst striking the tree, otherwise unnecessary strain will be placed on the pump and valve, and chemical will be ejected onto the bark. Use injector with groove in blade uppermost. Strike tree, cutting through bark to sapwood. Lower the upper end of the injector to open the cut, then move pump handle out and in
to inject the dose. A smooth action will give better results than a quick 'snapping' action.
• The chemical must be applied immediately after the dose pocket is made. 

B Cut Stump/Brushcutter Application
• Stems should be cut less than 10cm above the ground. Remove and treat the surface of any suckers present below the cut surface and ground level.
• Immediately apply Surefire TREESON Herbicide / water mixture liberally to the freshly cut stump by spraying the cut surface and sides of the stem.
• If cut surface is oily, add a 100% non-ionic surfactant (e.g BS-1000) at 100 mL/100 L water to improve penetration.
• When using a brushcutter with a herbicide attachment, read all safety and operating instructions in the brushcutter manual prior to use of the equipment.

C High Volume Spraying
Weeds need to be actively growing for herbicides to have optimum effect. In areas that have been bulldozed, slashed, burnt, ploughed or previously treated with chemical, wait until all regrowth has reached approximately 1 metre before treating.
• Thorough coverage of foliage to the point of run-off is essential, however, avoid excess spraying which is wasteful of chemical

Frequently Asked Questions

What is Surefire Treeson Herbicide used for?

Surefire Treeson is a powerful woody weed and tree killer herbicide designed for controlling unwanted trees, blackberry, gorse, harrisia cactus, and invasive woody weeds. It’s commonly used for cut stump treatment, stem injection, basal bark application, and foliar spraying in lawns, paddocks, fence lines, and non-crop areas.

How does Surefire Treeson Herbicide kill woody weeds and trees?

Surefire Treeson contains dual active ingredients — Triclopyr and Picloram — which move through the plant’s vascular system to kill the roots, stump, and regrowth from within. This systemic action helps provide long-lasting control of hard-to-kill woody weeds and tree species.

What is the best way to apply Surefire Treeson Herbicide?

The most common application methods are cut stump treatment and stem injection. For best results, apply the herbicide immediately after cutting the stump or making the injection cut so the active ingredients can enter the sap stream before the plant seals itself.

What weeds and trees does Surefire Treeson control?

Surefire Treeson is effective against a wide range of woody weeds and tree species including blackberry, gorse, camphor laurel, acacia, eucalyptus, melaleuca, casuarina, and harrisia cactus. It’s widely used for tree stump control and woody weed management in Australia.

How long does Surefire Treeson Herbicide take to work?

Visible results can appear within a few weeks depending on the weed species, plant size, weather conditions, and application method. Complete root and stump control may take longer for larger trees, but the systemic formula is designed to prevent regrowth and provide long-term woody weed control.
