The objectives of this experiment was to determine the effectiveness of herbicides in controlling weeds in lowland rice. The experiment was conducted from November 2012 to March 2013. Randomized block design (RBD) with 6 treatments and 4 replications was used. The treatments tested the herbicide Penoksulam 25.5 g/L dose of 0.60 L/ha, 0.75 L/ha, 0.94 L/ha, 1,125 L/ha, manual weeding and control. The experimental unit was a plots measuring 5 m x 5 m. The results showed that the application of penoksulam 25.5 g/L  could to control weeds of lowland rice. Dominance weeds species in tidal land were <em>Fimbristylis</em><em> littoralis</em>, <em>Ludwigia</em><em> octovalvis</em> and <em>Cyperus</em><em> Iria</em>. Application of herbicide at doses 0.60 L/ha up to 1.125 L/ha caused only mild symptoms of phytotoxicity on rice. Herbicides could be used to increase low land rice production on effective dose 0.60 L/ha to 0.75 L/ha.</p></div> ER -
