Weed control efficiency was assessed 60 and 90 days after sowing. Bentazon + 2,4-D controlled weeds in T141 and Mahsuri significantly better than IR36, perhaps because T141 and Mahsuri form a thicker canopy more quickly than semi-dwarf IR36. Weed weight differed from different rice varieties, but interaction between herbicide treatment and variety was not significant. Bentazon + 2,4-D gave significantly higher grain yield in T141 over hand weeding and bentazon alone. Results with bentazon would be different if grasses were the predominant weed species
