This research was conducted at peoples plantation area petaling jaya village, district of sungai gelam, regency of muaro jambi, province of jambi. Herbiside applied was with active isprophil amina gliphosate,2.4 D dimetiamina, and triasulphuron 75 %. Analysis of weed vegetation data was SDR value. The result of the analysis shours that there are 5 species that dominate. The 5 species are imperata cylindrica with SDR value 27,8%, Asystasia intrusa (9,4%), melastoma affinae (9,2%), panicum repens (8,2%), and boreria alato (7,7%). The application of herbiside with different active substance shows different displacement of weed domination..
