Biodiesel Waste Based New Generation Formulation of Permethrin for Cockroach Control

184-186Permethrin Microemulsion, Nanoemulsion & Emulsifiable concentrate was formulated using biodiesel waste as an active dissolving solvent or as a carrier solvent. Process of stable emulsion development was optimized for parameters such as non-ionic surfactants concentration in micro and nanoemulsion and anionic surfactant concentration in emulsifiable concentration with high physical and chemical stability. Permethrin was analyzed by Gas chromatography using ECD and physical stability of emulsions was optimized in terms of shelf life of the product. The permethrin microemulsion (ME) , Nanoemulsion (NE) and emulsifiable concentrate (EC) containing biodiesel waste of 20-100 ppm gave 30 -90 % mortality rates against Periplaneta americana (Order: Blattodea, Family: Blattidae) within 24 hours. The LD50 (Lethal dose) values recorded for the microemulsion, nanoemulsion and emulsifiable concentrate were 6.7646,10.385 & 46.7289 with biodiesel waste as a solvent or carriers for above formulations
