Developing an Integrated Weed Management (IWM) Plan
Integrated weed management (IWM) is a system for managing weeds over the long term, and is particularly useful for managing and minimising herbicide resistance. An integrated weed management plan should be developed for each paddock or management zone based on five steps: review past actions; assess the current weed status; identify weed management opportunities within the property and match the weeds to the most suitable control technique.
IWM Plan Development
An integrated weed management plan should be developed for each paddock or management zone based on six steps.
Map your property
Identify the weeds on your property
Review past actions. The history of herbicide use can be used to prioritise weed management tactics to avoid the use of high risk herbicide mode-of-action groups and identify those paddocks at risk.
Identify weed management opportunities within the property. Ensure that the proposed changes to the weed management system are suited to the land; infrastructure, resources and the tactics are environmentally and economically sound.
Match the weeds to the most suitable control technique
Prevent weed seed introduction
In a well-integrated weed management plan, each target weed will be attacked using the most suitable method that is the least toxic to people, livestock and the environment. Each technique provides a key opportunity for weed control and is dependent on the management objectives and the target weed’s stage of growth. Successful weed management also relies on the implementation of the best pasture and crop management to reduce the opportunity for weeds to become established. i.e. a healthy pasture is resistant to weed invasion by having a balance between pasture, soil nutrition and grazing or pasture management that does not allow weeds to establish.
