This research conducted on the month August to November 2017 in the Pucangan Village, Kartasura Subdstrict, Sukoharjo District. This research used a complete randomized block design with one factor, twelve treatments and repeated 4 times, one the treatment of which is a control. Treatment of rinskor and penoxsulam herbicide combination with dose 750 ml/ha, 1000 ml/ha and 1250 ml/ha as wall as comperative herbicides penoxsulam & sihalofop (500 ml/ha & 800 ml/ha), penoxsulam (800 ml/ha), Natrium byspiripac (300 ml/ha), metil metsulfuron, etil klorimuron, 2,4D natrium (600 ml/ha), metil metsulfuron, 2,4D natrium, etil klorimuron (250+500 ml/ha), fenoksaprop etil dan etoksisulfuron (700 ml/ha), manual and control. Observed result were analyzed, if there is a real difference with a level of 5% will be tested continued using Skott Knott test at 5% confidence level. The result showed that rinskor and penoxsulam herbicide combination, starting with a dose 1000 ml/ha to 1250 ml/ha can control weeds better than other treatments and produce the highest yield of rice crops.

Penelitian dilaksanakan pada bulan Agustus – November 2017 di Desa Pucangan, Kecamatan Kartasura, Kabupaten Sukoharjo. Penelitian menggunakan metode Rancangan Acak Kelompok Lengkap 1 faktor dengan 12 perlakuan dan 4 ulangan, satu perlakuan diantaranya merupakan
