This manual outlines the ecology and threat of hymenachne, discusses a range of control methods, and provides planning tools to assist in weed control. It also covers the impact of ponded pasture species and provides some information on native
hymenachne (Hymenachne acutigluma). The information presented in this manual is based on a review of published information, a study of field practices, and a survey of technical experts and weed managers. In addition, the manual contains a number of case studies that give practical examples of how hymenachne is being managed or utilised in various parts of northern Australia.
