Effective weed management is a critical factor in attaining profitable rice production in all regions of the world. In Australia where rice is produced as an irrigated summer crop, yields must be high (typically > 9 t/ha) in order to be profitable in comparison to competing uses for the limited irrigation water. Australian ricegrowers aim for freedom from weed competition throughout the life of the crop and particularly the first 45 days after seeding. In order to achieve this, precision field leveling, clean seed, weed free seedbeds and rapid inundation are integrated with timely and accurate herbicide application. The Australian rice industry has long recognised the importance of effective weed management with constant investment in weed control research for nearly 30 years. Agropraisals Pty. Ltd. have assisted with this research for the past decade. 2004, 41pp, Pub No 04/001, $16
