Sari. Pengendalian gulma pada budidaya padi sawah perlu dilakukan, karena gulma dapat menyebabkan penurunan hasil padi sawah. Penelitian bertujuan untuk mengetahui keefektifan campuran herbisida Bentazone sodium dan MCPA DMA dalam mengendalikan gulma pada budidaya padi sawah. Percobaan dilaksanakan pada bulan November sampai bulan Desember 2017 di Kecamatan Ciparay Kabupaten Bandung. Rancangan percobaan yang dilakukan yaitu Rancangan Acak Kelompok dengan tujuh perlakuan dan empat kali ulangan, percobaan yang diuji yaitu: campuran herbisida Bentazone sodium + MCPA DMA dosis 0,75 L/ha; 1 L/ha; 1,25 L/ha; 1,5 L/ha; 1,75 L/ha; penyiangan manual, dan tanpa perlakuan (kontrol). Hasil percobaan menunjukkan bahwa perlakuan campuran herbisida Bentazone Sodium + MCPA DMA 0,75 L/ha efektif mengendalikan gulma Fimbristylis miliaceae, Ludwigia adscendes, Cyperus difformis, dan Leptochloa chinensis dan tidak menimbulkan keracunan pada tanaman padi. Campuran herbisida Bentazone Sodium + MCPA DMA 0,75 L/ha – 1,75 L/ha dapat meningkatkan bobot biji kering padi.Kata Kunci: Bentazone sodium, MCPA DMA, Herbisida Campuran, PadiAbstract. Weed control in rice cultivation must be improved, because weeds can decrease rice yield. The purpose of this experiment was to quantify the effectiveness of herbicide mixture of Bentazone sodium and MCPA DMA in controlling weeds on rice field. The experiment was conducted in Ciparay district, Bandung Regency, from September to Desember 2017. The experiment used experimental method. It used Randomized Block Design (RBD) that consisted of 7 treatments and 4 replications. The treatment was dosage 0,75 L/ha; 1 L/ha; 1,25 L/ha; 1,5 L/ha; and 1,75 L/ha of herbicide mixture Bentazone sodium + MCPA DMA, Manual weeding, and Without treatment (control). Dosage 0,75 L/ha of herbicide mixture of Bentazone sodium + MCPA DMA effectively control weeds Fimbristylis miliaceae, Ludwigia adscendens, Cyperus difformis, and Leptochloa chinensis. Herbicide mixture of Bentazone sodium + MCPA DMA at all tested doses showed that there was no symptoms of herbicide toxication in rice crops. Herbicide mixture of Bentazone sodium + MCPA DMA at dose 0,75 L/ha – 1,75 L/ha improved dry grain weight.Keyword ; Bentazone sodium, MCPA DMA, mixture herbicide, rice
