The development of integrated crop management practices means that integrated weed management (IWM) systems have been developed that also embrace environmental and financial factors. The IWM systems need to be effective enough for long‐term maintenance of natural resources and agricultural productivity and also to have minimal adverse environmental impact combined with adequate economic returns to the farmer.

Key aspects of IWM systems include the prevention of weed infestation, the identification of weed species that are present, the mapping and monitoring of weed populations, the prioritisation of management, management using a combination of mutually supportive techniques (manual, mechanical, cultural, biological and chemical methods) and evaluation of their success combined with documentation and perseverance.

Through the use of such systems it is hoped that weed management may be carried out in a sustainable manner, giving protection to both financial returns and to agroecosystems.
