Management of Noxious Weeds
One of the most effective ways to control noxious weeds is through Integrated Pest Management (IPM), a system by which one or more techniques are brought together to create management plan for the land owner to address their specific needs and challenges.
An IPM can provide optimum control of weeds, however, it doesn’t mean that multiple techniques have to be used, nor does it mean chemical control options can never be used.

Methods of Control
The most effective, economical and ecologically sound technique, often the spread of noxious weeds can be limited or contained simply by careful practices:
- Control or Limit Seed Dispersal
- Clean equipment, vehicles, clothing and shoes when leaving a known infected area and before entering a non-infected area.
- Contain animals who have grazed in infected areas for 2 weeks in a dry lot, before moving them to grazing areas not infested.
- Manage existing vegetation wisely – Do not overgraze grasses to the point they struggle to compete with weeds.
- Minimize soil disturbances which encourage the germination of weed seeds.
- Use certified weed-free seed and feed in your operations
- Use weed-free sand, soil and gravel for projects.
- Monitor regularly to detect and implement control of new infestations early.
- Support existing competitive vegetation through fertilization, irrigation, re-seeding.
- Establish competitive vegetation, such as grasses and forbs, which often compete well with weeds in most cases.
- Practice good Grazing Management practices to maintain the health of your native or desirable vegetation
The use of insects, diseases or grazing animals can be used in large, heavily infested areas, though these methods are not desirable when eradication is the goal. Biological techniques are often used to reduce the dominance of noxious weeds.
Whether by hand or with equipment, mechanical techniques concentrate on removing, killing, injuring or altering the growth phases of invasive species. One or more of the following methods may be appropriate:
- Clipping Seedheads
Herbicides suppress or kill weeds by disrupting the biochemical process unique to certain plants.
To control infestations, start at the outer edges and work inward; always monitor roadsides, railways and waterways.
