Access Herbicide is a specialised herbicide for robust control of almost any woody weed via the cut stump or basal bark application technique. Access Herbicide offers a solution for very targeted woody weed control in environmentally sensitive situations, commercial and industrial areas, public lands, fence lines and pastures.
Access contains the active ingredients Triclopyr (240g/L) and Picloram (120g/L), which have activity on a range of broadleaf weeds. Access is classified as a Group I Herbicide, with a mode of action where the weed cannot grow due to disruption of plant cell growth.
Access is registered for selective control of a wide range of woody and noxious weeds in commercial and industrial areas, public lands, fence lines and pastures, by basal bark and cut stump applications.
A new technique to apply Access and diesel has recently been approved for use called ThinLine application. The same equipment is used for both techniques – the difference is the height of the stem that needs to be treated and the dilution rate.
Access Herbicide Application Methods:
The cut stump method involves cutting off the weed completely at its base (no higher than 15cm from the ground) using a chainsaw, axe, brush cutter or machete. A herbicide solution (such as Access) is then sprayed or painted onto the exposed surface of the cut stump, with the objective of destroying the stump and the root system.
It is essential that the herbicide solution is applied as soon as the trunk or stem is cut. A delay of more than 15 seconds for water-based herbicides and 1 minute for diesel-soluble herbicides will give poor results.
This method involves mixing an oil-soluble herbicide in diesel and spraying the full circumference of the trunk or stem of the weed.
Basal bark spraying is suitable for:
- thin-barked woody plants
- undesirable trees
- saplings, regrowth, and multi-stemmed shrubs and trees.
Basal barking will usually destroy weeds as long as the bark is not wet or too thick for the Access Herbicide and diesel to penetrate.
