The Effect Concentration Plant Extracts Bintaro(CarberaManghas)Against Mortality Hama armyworm (Spodopteralitura)
This study aims to determine the effect of combined treatment plant extracts bintaro and giving the extract concentration on the mortality of armyworm pests.

Treatment Factor I was the Bintaro plant organs extracted consisting of 4 levels consisting of 4 combinations of Bintaro organs and 5 combinations of extract concentrations so that there were 20 combinations and 1 control (without giving the extract) so that a total of 21 treatments were repeated 3 times, a total of 63 units. trial.
