Types of control methods

Physical control

Physical weed control refers to manually removing weeds either by hand, or using tools or machinery.

|

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.

Slashing Gamba grass

A blade plough is used to push over some woody shrubs and cut their roots underground.

Example of a blade plough

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 needed.

Bulldozing chinee apple

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 needed.

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.
