Twenty weed species belonging to 15 families were found in rice fields near Kampung Tandop, in the Muda Irrigation Scheme, Kedah, Malaysia. The dominant weeds in dry-seeded rice were Utriculatia aurea Lour., Fimbristylis miliacea (L.) Vahl., Echinochloa cruss-galli (L.) Beauv., Monochoria vaginali...

In the wet-seedled rice, the dominant species were N. graminea, Lemna minor L, Sphenoclea zeylanica Gaertn., U. aurea, and Sagiuaria guayanensis H.B.K. while in volunteer seedling rice fields, the dominant species were Echinochloa colollllm (L.) Link., Fimbristylis alboviridis C.B. Clarke, F. miliacca, Cyperus babakan Steud. and Fuirena umbellata Rottb.. Dry-seeded rice fields contained the highest number of weed seeds (930,910/m2. in the top 15 inch of soil); volunteer seedling rice fields contained 793, 162/m2 and wet-seeded rice fields 712,228/m2. In general, seed number declined with increasing soil depth. At 10-15 cm depth, seed of U. aurea and S. zeylanica were tile most abundant in dry- and wet-seeded rice fields, whilst seeds of Scirpus juncoides Roxb. and F. miliacea were most abundant in volunteer seedling fields.
