Weeds

Integrated Weed Management (IWM) combines multiple weed control methods in a long-term plan to effectively manage infestations. It includes four main approaches:

• Physical control – removing weeds by hand or slashing.

• Chemical control – applying herbicides.

• Biological control – introducing natural enemies, such as blackberry leaf rust.

• Cultural control  – adjusting land use to suppress weeds.

Most weeds require more than one method for effective control, and the best approach depends on location, environment, and resources. IWM also considers the impact on native ecosystems and aims for minimal harm.

A well-planned IWM strategy prevents wasted time, money, and effort by ensuring the right techniques are used at the right time. It is particularly useful for tackling multiple weed species, prioritising high-risk weeds, and preventing further spread.
