Abstract: | Weeds are one of major problem in rice intensification. The objective of this research was to observe the effectiveness of bentazon and MCPA as mixed herbicide to control weeds in rice. The experiment was conducted at Bojong Jengkol village, Ciampea district, Bogor regency, West Java from September 2012 until January 2013. This research was arranged in Randomized Block Design with single factor, seven treatments and four replications. The treatments consist of seven treatments with five dosages of herbicide (i.e.: 1.00 L ha-1, 1.50 L ha-1, 2.00 L ha-1, 2.50 L ha-1, and 3.00 L ha-1), conventional weeding (at third and sixth week after transplanted) and no weeding. The result showed that bentazon-MCPA application could control sedges (Fimbristylis miliacea and Cyperus iria) and broadleaf (Ludwigia octovalvis, Alternanthera philoxeroides, and Portulaca oleracea) weeds. Application of bentazon-MCPA caused light-fair toxicity symptomps on rice plants until 2 weeks after application and decreased empty grain percentage about 6-10 % compared with no weeding treatment also increased rice yield productivity about 48.6% and that was not significantly different compared with conventional weeding. |
