Weed Biology and Management aims to extend current knowledge in weed science with the publication of peer- reviewed original research articles and reviews relating to weed taxonomy, ecology and physiology, weed management and control methodologies, herbicide behaviors in plants, soils and environment, utilization of weeds and other aspects of weed science. The Journal welcomes contributions from weed scientists in the Asia Pacific region in particular and is published with the cooperation and encouragement of many of the national weed science societies affiliated with the Asian-Pacific Weed Science Society (APWSS).
