4ML SPOT GUN - SOIL & STEM INJECTOR (For use with Hexazinone / Velpar)
1 x 4mL Handgun & Draw-off tube which is used for soil application and stem injection
1 x 5L BackPack & Straps (Suitable for Hexazine Herbicide.)
1 x Service Kit (Seal, Spring & Valve)
WHY THE 4ML SPOT GUN / SOIL INJECTOR IS SO EASY TO USE:
Instead of being mixed with Diesel or water, Hexazinone Herbicide is applied undiluted through the Spot Gun. Fill the backpack with straight Hexazinone and you are ready to go. There is no mixing, no heavy hoses to drag around, no heavy knapsack on your back and virtually no effort. You can forget about all the time wasted setting up equipment and mixing sprays. Its a go anywhere system and you can use it anytime.
4ML SPOT GUN / SOIL INJECTOR MAINTENANCE:
It is essential to clean the 4mL Spot Gun after each use. The easiest way is to put warm water in the backpack and pump it through the Spotgun. Be careful that the wastewater does not drain onto any desirable plants. To make the 4mL Spot Gun easier to use, it is recommended to pump Castor Oil or Vegetable Oil through it before commencing applications.
The 4mL Spotgun delivers a metered dose of Hexazinone Herbicide which is directed onto the soil, not the trunk, at the base of the plant and within the dripline. From here it is moved into the soil by rainfall where it is taken up by the roots and then moves to the leaves.
The rate of application and the number of spots depends on the height of the plant to be controlled, and the species. The grid application pattern should be used where suckers are forming a dense ground cover. If there is leaf litter underneath the plant, clear a small area then apply the Hexazinone Herbicide. See Hexazinone Herbicide directions of use for full instructions.
The soil application technique should be used;
The spear attachment (sold separately) should be used on sloping ground and when heavy leaf litter is beneath the plant. Place the spear on the high side of the bush about 2cm into the soil.
The stem injection technique offers a more economical method of controlling larger regrowth than the soil application technique.
Make axe cuts with a narrow bladed axe (5-7cm wide) into the sapwood just under the bark at waist height. Do not cut into the hardwood. Inject the metered dose of Hexazinone Herbicide while the axe is still in the cut and within 5 seconds of making the cuts. Chemical uptake is dependent on good sap flow. The number of cuts will depend on the circumference of the tree. See Hexazinone Herbicide directions of use for full instructions.
For multi-stemmed trees, treat each stem as an individual tree.
The Stem Injection Technique is used for larger regrowth timber when selectivity is important. Stem Injection is more economical than soil applications in this situation.
Once in the soil, Hexazinone Herbicide is taken up by the roots and translocated within the plant. It works by inhibiting the photosynthesis process, starving the plant to death. This is a slow process. The plant may not appear affected for a while (particularly under dry conditions) and may defoliate and refoliate several times before it completely dies. Complete control normally occurs within 12 months however under adverse conditions it sometimes may take longer.
