Abstract

Pesticide should be formulated to keep bioactivity and to enhance efficiency and safety in application. Insecticide formulations consist of active ingredient and co-formulant. Most active ingredients are poorly diluted in water, so they need adjuvant such as surfactant. Surfactant will help to make a homogeneous solution between formula and water. Insecticide was formulated using emamectin benzoate as active ingredient and co-formulants such as xylene as solvent, surfactant DEA, APG and CTAC. DEA and CTAC surfactants were synthesized from palm oil derivates. They were palm oil methyl ester and palmityl alcohol. Insecticide was formulated using emamectin benzoate 15%, non-ionic surfactant (4%, 5%, and 6%) with DEA: APG ratio of 3:2, 1:1 and 2:3 and also cationic surfactant of 1%. Characterization of insecticide formulation showed that the best formulation of concentration nonionic surfactant was 6% with DEA: APG ratio of 2:3. The best characteristic of insecticide formulation was density of 0.9955 d/cm3, surface tension of 27.42 dyne/cm, contact angle of 21.61, and particle size of 4.64 μm. This formula also caused mortality of Spodoptera litura, one of major insect pests on soybean, and showed as effective as commercial insecticide formula. The best insecticide concentration for application was 0.20% that caused 96% of larvae mortality at 24 hours after application.
