Weed Control Methods

The method of control to be used must be assessed for each individual situation and as approved by the Local Control Authority. An important consideration when one removes a weed from a situation is what to replace it with. If the ground is left bare then the soil may erode or another plant may grow back in its place. Unless a useful species is introduced it is likely that another weed of the same or different species may invade the area.

The consideration of all factors involved in the environment when destroying weeds is known as Integrated Pest Management. Your Local Council Weeds Officer can give professional advice, NSW Agriculture is also available to assist.

PASTURES - In grazing country improved pastures are an ideal way of replacing weeds. Quite often weeds only invade pasture because the pasture is weak from poor nutrition, disease or insect damage. Managing these problems may be a better long term control, than just killing the weed.

BIOLOGICAL CONTROL - Biological Control (BC) can be effective in controlling but rarely if ever eradicating a weed. BC is the introduction of an insect or pathogen that attacks the weed. BC agents have varying success but are usually best accompanied by other means of control.

REAFFORESTATION - Planting forests can assist in weed control. It should be remembered that most trees do not assist to any degree in weed control until there is a total leafy canopy. This may take 5-10 years. During the establishment phase, weed control can be critical to the success of the plantation.

PHYSICAL REMOVAL - Cultivation has been the most widely practiced weed control measure in farming country and in the gardens. Care must be exercised to prevent soil degradation due to excessive cultivation or cultivation at the wrong time. Care must be taken to ensure compliance with other Acts.
Hand pulling may help control weeds such as Groundsel Bush but may actually spread others such as Johnson Grass. Pulling plants with seed on them may spread the seed to clean areas.

HERBICIDES - Herbicides are quite often the most effective and cost efficient means of weed control. Care must be taken to only use herbicides for the purposes and under the conditions outlined on the label. Care should be exercised to minimise the impact of herbicides on the environment and on to non-target species.

CONTRACT WEED CONTROL - Most Local Weed Control Authorities keep a list of approved weed control contractors and /or provide contract service for all weeds, not just for noxious weeds. Ring them for details.
