The treatments tested were the rates of active ingredient of penoksulam at 1.2 ml plot-1, 1.8 ml plot-1, 2.4 ml plot-1, 5.0 ml plot-1, 12.0 ml plot-1, and with no herbicide added (control). The experimental plots had a dimension of 4 m x 5 m each. The herbicide at the rates up to 12.0 ml plot-1 added at 3, 7 and 14 days after application only caused mild symptoms on the rice plants. The dominant weeds controlled by the herbicide included Fimbristylis miliacea, Echinochloa crusgalli, Ludwigia octovalvis, Monochoria vaginalis, Cyperus iria, Cyperus difformis, Leptochloa chinensis and Limnoharis.
