In order to study the efficacy of new herbicide Bazagran (bentazon + MCPA, SL 46%) in the control of broadleaves and sedge in paddy fields, an experiment was conducted at Rice Research Institute in the 1397 crop year.the doses of 0, 575, 1150, 1725 and 2300 (g.ai.ha-1) of Bazagran in comparison with the recommended dose of commonly used herbicides Nominee (SC 10%, 25 g.ai.ha-1), Cleanweed (SC40%, 40 g.ai.ha-1) and Stam (EC 36%) were investigated.The results showed that the efficacy of Bazagran and Stam in the control of bulrushwas observed three days after treatment and it peakedwithin 10 days, while the first symptoms of the effect of Nominee and Cleanweed appeared about three weeks after treatment. The efficiency of recomended dose of bazagran to controll bulrush in the field ranged from 60 to 85 percent but it was more than 90 percent for Nominee and Cleanweed. bazagran had insufficient efficacy (50%) in control of barnyardgrass but, very good performance (about 100%) on monochoria (monochoria vaginalis), water-plantain (Alismaplantago-aquatica) and false daisy (Eclipta prostrate). generally, according to the results, based on weed density a range of 2 to 2.5 liters of bazagran is recommended for broadleaf and sedges control in paddy rice.
