Physical weed control refers to the manual removal of weeds either by hand, or using tools or machinery.
Hand pulling and grubbing
Weeds, including their roots, are physically pulled out of the ground by hand or using hand tools.
This is an effective method of control for individual weeds and recent outbreaks that haven’t released seeds yet, but it requires a lot of labour.
A brush-cutter, slasher or mower are used to cut weeds off above the ground level. This can be effective in suppressing flower and seed development.
A blade-plough is used to push over some woody shrubs and sever their roots underground.
Bulldozers, chopper rollers or graders are used to clear large weed infestations. This leaves large areas of soil exposed so follow up control or revegetation is almost always necessary.
A large blade with teeth attached to a bulldozer is used to clear large weed infestations.
This leaves large areas of soil exposed so follow up control or revegetation is almost always necessary.
A large heavy chain is dragged across the ground by heavy machinery to push over and pull out large weeds.
This method is useful for removing roots and providing access for burning. It works best at the end of the wet season when the ground is soft and roots are easier to pull from the soil.
