Enhance the physicochemical properties of the citronella oil -SLNPs to improve the insecticidal activity against (Boisd) (Lep. Nactuidae).

The Nano-formulation of citronella essential oil ( (L.) and their mixtures of three adjuvants (Provecta®, Top film®, and PEG600-dioleate) were studied to enhance physico-chemical properties of the Nano-formulation and improve the insecticidal effect against (Boisd). Characterisation of physicochemical properties of Nano-formulation was studied by calculating droplet size, polydispersity index (PDI), and Zeta-potential parameters.
