One of the factors to production of the rice paddy is the environment the existence of weeds which growth and yield of rice paddy. Weed control using the chemical method of using herbicides is more effective than other weed controls.This research aims to review the efficacy of Metsulfuron Methyl herbicide the growth and yield of rice (Oryza sativa L.). This research was conducted in Desember 2018 – April 2019 in SPLPP (Sanggar Penelitian Latihan dan Pengembangan Pertanian), Baleendah District, Bandung Regency, West Java.This design used was a Randomized Block Design with 7 treatments and 4 replications. The type of treatment in this research consited of : Metsulfuron Methyl herbicide at a dose of 10g/ha, Metsulfuron Methyl herbicide at a dose of 15g/ha, Metsulfuron Methyl herbicide at a dose of 20g/ha, Metsulfuron Methyl herbicide at a dose of 25g/ha, Metsulfuron Methyl herbicide at a dose of 30g/ha, weeding 3 and 5 MST, control (without weeding and without herbicides). The difference between treatments was tested using the Duncan test at real level of 5 %.The result showed that Metsulfuron Methyl herbicide at a dose of 20 g/ha were able toLudwigia perennis, Fimbristylis miliacea, Limnocharis flava, Leersia hexandra and Monochoria vaginalis can control weeds and influence the growth and yield of rice plants.
