The resistance status of Eleusine indica to the isopropylamine glyphosate herbicide leads control losses in oil palm plantations. Appropriate management is needed reduce presence glyphosate-resistant E. indica. This study aimed obtain recommended sequence or pattern pre- and post-emergence herbicides controlling biotypes. was conducted Telaga Sari Village, Sunggal Subdistrict, Deli Serdang District, North Sumatra, Indonesia from January August 2019. seeds were used a confirmed highly biotype at 1,080 g ai ha-1. factorial Randomized Block Design with four replications. first factor type 1 l ha-1, respectively. second Parameters analyzed by ANOVA subsequently followed DMRT P < 0.05 IBM SPSS. Results showed that pre-emergence more effective biotypes classified as excellent than similar dose. percentage capability pre-and indaziflam oxyfluorfen > pendimethalin propaquizafop potassium mesotrione. performance very good compared other post-emergent herbicides.
