Weed control is the botanical component of pest control, which attempts to stop weeds, especially noxious or injurious weeds, from competing with desired flora and fauna, this includes domesticated plants and livestock, and in natural settings, it includes stopping non local species competing with native, local, species, especially so in reserves and heritage areas.

Environmental management aims to alter the conditions required by a particular weed.
Fire, moisture and nutrient control, and over-planting
Chemical control
Chemical control involves the use of herbicides. Herbicides control weed plants either by speeding up, stopping or changing the plant's normal growth patterns; by desiccating (drying out) the leaves or stems; or by defoliating the plant (making it drop its leaves).
Types of herbicides
Labels and permits
It is extremely important to read and adhere to the information contained on the herbicide label. By law, herbicides can only be used in accordance with the claims for use on the label. Most environmental weed applications are not listed on herbicide labels. In these cases, it is necessary to obtain an off-label permit.
Safeguard and label information
Off-label permit 11463
Control techniques
Some techniques are more suitable for control of particular species and in different situations than are others.
Foliar spraying
Basal bark spraying
Stem injection
Cut stump
Cut and swab
Stem scraper
Wick applicators
Mechanical control
Mechanical control is the use of powered tools and machinery to manage weeds. It is suitable for larger infestations because it reduces the weed bulk with less manual effort. Care should be taken to minimise soil disturbance.
Slashing, mowing, dozing, pushing and felling
Biological control
Biological control involves the use of insects or pathogens (diseases) that affect the health of the weed. Usually, these biocontrol agents are from the same country of origin as the weed spec
