Abstract
This study aims to find and obtained the exact concentration of tuba root powder to control Aphis glycines on soybean (Glycines max L. Merrill). The research conducted experimentally using Completely Randomized Design (CRD) with 6 treatments (T0 = 0%; T1 = 0,2%; T2 = 0,4%; T3 = 0,6%; T4 : 0,8% dan T5 = 1%) and 4 replications. The data has been analyzed using variance and further using Duncan's New Multiple Range Test at the 5% level. The results showed that 0.6% tuba root powder is effective to control aphids A. glycines because it is able to kill A glycines up to 91.66%. Based on probit test using POLO program, lethal concentration 50% (LC50) A. glycines is 0.14% or 0-0.2% and lethal concentration 95% (LC95) A. glycines is 0.69% or 0.6-0.8%.
