Abstract

This study aims to determine the rate of metsulfuron-methyl herbicide effectively controlling weeds in rubber plantations, determine changes in weed composition due to metsulfuron-methyl herbicide application, and determine whether phytotoxicity of rubber plants occurs after the application of metsulfuron-methyl herbicide. This research was conducted at farmers farm in Onoharjo Village,Terbanggi Besar Subdistrict, Central Lampung Regency and Weed Laboratory of the Faculty of Agriculture, University of Lampung during December 2017 to March 2018. This research used a randomized block design (RBD) with six treatments and four replications. The treatments are metsulfuron-methyl herbicide at15 g/ha, 20 g/ha, 25 g/ha, 30 g/ha, mechanical weeding, and control plot. Homogenity of data was tested by the Bartlett test, data additivity was tested by the Tukey test, and differences in the mean value of the treatments were tested with the Least Significant Difference (LSD) test at 5% level. The results showed that metsulfuronmethyl herbicide 15-30 g/ha was effective in controlling total weeds, broad leaf weeds, Borreria alata, and Praxelis climatidea at 4 - 12 weeks after application. Metsulfuron-methyl herbicide15-30 g/ha controled weed grass and sedges at 4 - 8 weeks after application. Metsulfuron-methylherbicide15-30 g/ha controls weed Axonopus compressus, Croton hirtus, and Ottochloanodosa at 4 weeks after application. Application of metsulfuron-methyl herbicide 15-30 g/ha resulted in change in composition of weeds at 4, 8 and 12 weeks after application. The application of metsulfuron-methyl herbicide 15 - 30 g/ha didn’t cause rubber phytotoxicity.
