This update to FAO's original 'Weed management for developing countries' reflects recent progress in weed control on a number of fronts. Two opening papers emphasise the importance of weed ecology in understanding how to tackle weed problems. They discuss protocols for assessing weed seed banks, and tools for analysing weed-crop competition. A third paper describes new work on weed risk-assessment, and the use of quarantine procedures to restrict spread of alien species. This is followed by a collection of studies covering recent progress in the control of some particular problem weed species. Each study gives basic information about the biological characteristics and economic importance of the weed, followed by a review of management options. An integrated approach to control, combining cultural, mechanical, chemical and sometimes biological methods, is often advised. Weed species covered include itchgrass, speargrass, the parasitic weeds orobanche and striga, water hyacinth, and wild rice. A final section of papers focus on particular management methods, including use of cover crops, and strategies to deal with herbicide resistance in weeds. Overall the papers provide a useful overview of current research.
