Effect of Biopolymer Matrix on Slow Release Capacity From Biopesticides Based on Citronella Oil

Abstract . Some biopolymer materials can be used as filler to increase the slow release capacity of active component. Technology modification biopesticide production processes its use sodium alginate, maltodextrin and CMC (Carboxy Methyl Celluose). The purpose this research activity was modify formulation several types concentrations biopolymers analyze characteristics in citronella oil-based biopesticides. method carried out stages including: produced nano emulsions, added matrices analyzed their well biopesticides with oil ingredients. concentration ranges are 1, 2 5%. While addition done using 0.5, 1 2%. Based on results study showed that maximum 2% 1%. Whereas Sodium alginate unstable products separate solutions. size droplet has a range between 131.8 177.1 nm. analysis components dl-Limonene experiencing fluctuating releases during 0 12 days. next requires optimization activities before implementation at field level.
