Abstract
Eleusine indica is one of the weeds that the existence detectable almost field or plant cultivation, especially in oil palm plantation areas estate. One of the methods to control this weed is with herbicide applications. The used of one kind of herbicide with a continuously and long time can cause weed resistance to this kind of herbicide. The researched purposed is to determine the response of two population E. indica to glyphosate herbicide. The research used Randomized Block Design with three replication and five variations of treatment dose for an herbicide that are: 60,75 grams active ingredients/ha, 121,5 grams active ingredients/ha, 243 grams active ingredients/ha, 486 grams active ingredients/ha and 972 grams active ingredients/ha. The highest rate of herbicide resistance was found in the ER1 population at 6 Week After Application where the Lethal Dose 50 glyphosate value in this population was 16 times greater than the comparison population. E. indica from ecotype ER1 has been resistant to glyphosate herbicide. Giving glyphosate herbicides significantly affected E. indica originating from both ecotypes, namely ER1 and ESP on weed number parameters surviving at 3 Week After Application and 6 Week After Application. While the administration of glyphosate herbicide has a significant effect on E. indica from ESP ecotypes on the parameters of the number of tillers at 6 Week After Application.
