This RIRCD report presents information on green and brown slime for the rice industry and its stakeholders. The report presents information on the study investigating the causes and management of slimes affecting rice production in the irrigation area of Southern NSW. A description of the components and causes of slime and recommendations for control are included. The aim of the project was to identify and control green slime, determine the nature of brown slime and why it is problematic, determine the conditions that increase brown slime and suggest strategies that famers can use to reduce the slime problems. These aims were undertaken by using field observation by both farmers and researchers and experimental evidence obtained in the laboratory. The report concludes there is a greater chance of rice sown into flooded bays containing urea to have greater chance of brown slime to grow faster that rice. In this case there is greater chance of brown slime formation which interferes with rice establishment and in some case decrease in yield.
