Effect of beluntas leaf (Pluchea indica) ethanol extract on mortality of instar II larvas (Spodoptera litura F.) on long bean plant (Vigna sinensis L.)

Low long bean productivity is one of the impacts S. litura. Farmers often rely on chemical fertilizers to control population litura so that this method can leave residues in growing media. Therefore, an effort overcome problem use natural pesticides from beluntas leaves (P. indica), which produce secondary metabolites. This study aimed determine effect ethanol extract indica) mortality second instar larvae plants. used a completely randomized design (CRD) consisting 5 concentrations, namely 50 ppm, 100 150 200 and 250 as well using distilled water with two repetitions. Descriptive statistics analyzed research data. The results showed affected by 40.0% at concentration ppm. Concentrations ppm gave 10.0%, was 15.0%, 35.0%. Thus it be concluded higher leaves,
