Natural pesticides are commonly used active ingredients that are naturally non-chemical synthetic. The present work was to evaluate the changes in the quality of natural biopesticides formulated from rice husk liquid smoke during storage for 6 months. The formulation of biopesticide was carried out in the form of emulsified concentrate (EC) has 3 formulas (F1, F2, and F3). The physical properties were characterized by the observed pH, specific gravity, phase separation, particle size, and PDI (polydispersity index). The particle size tended to increase during the storage, however, PDI only F3 was increased and F1 and F2 fluctuated. Moreover, neither pH nor specific gravity changed significantly after six months of storage. pH and specific gravity ranged from 3.11 to 4.31 and 1.0179 to 1.0309, respectively. There was phase separation on all formulas, where F1 and F2 showed lower separation than F3 after 6 months of storage. The phase separation ranged from 71.42 to 92.86 %. This study provides information that natural pesticides can be stored for 6 months with slight changes in their physicochemical properties.
