Abstract: The presence of weeds in a lowland rice field (Oryza sativa L) results in a decrease in rice crop production. Weed control using herbicides is an effective and efficient way compared to mechanical control techniques. This study aims to determine the effectiveness of Cyhalofop-butyl 100 g / l herbicide against weeds in lowland rice cultivation and its effect on rice plant growth. The experiment was carried out in Tomo Subdistrict, Sumedang Regency, West Java and weed science laboratory, Faculty of Agriculture, Padjadjaran University from April 2019 to August 2019. The experiment used a Randomized Group Design method with 7 treatments and 4 replications. The experimental treatments included: Cyhalofop-butyl herbicide at a dose of 50 g / ha; 75 g / ha; 100 g / ha; 125 g / ha; 150 g / ha; mechanical weeding and control (without treatment). The results showed that: Herbicide with active ingredients Cyhalofop-butyl 100 g / l was effective in controlling weeds found in rice paddy plants. Application of Cyhalofop-butyl 100 g / l herbicide has a good effect on the growth of the number of vegetative tillers per clump, the number of productive tillers per clump, and the weight of dry milled unhusked rice and does not cause poisoning in rice plants.
