Anti-microbial and Anti-insecticidal activity along with GC-MS report of Lantana camara and development of Innovative Insecticide

Abstract

Weeds are still major problem in all over the World. Human society is unable for total eradication of weed till today. It is demand of time that we must move towards positive aspect of weeds. Present work is based on the same strategy, in which an innovative product is developed using the leaves of Lantana camara. The leaves of the L.camara have fungicidal, antibacterial and insecticidal activities. During the process of development of product ethanolic extract of leaves was analysed for its antimicrobial analysis, secondary metabolite analysis and activity against insects. Antimicrobial activity was tested against three pathogenic bacterial strains i.e.; Micrococcus luteus, Citrobacter freundii, Staphylococcus aureus and two fungal strains i.e.;Aspergillus niger and Paecilomyces sinensis. The fungi Paecilomyces sinesisis an Entomopathogenic fungi, that infect and kill harmful insects. In some cases, it is also found as Endophytic fungi. The maximum zone of inhibition was found in Citrobacter freundii and Aspergillus niger when tested with 10% concentration of ethanolic extract of L.camara. Secondary metabolite analysis was performed using GC-MS,which reveals 27 compounds. The research reveals that Diethyl Phthalate has the maximum area percent in this ethanolic extract which is mainly used in insecticides. Anti-insecticidal activity was analyzed on the plant Calotrope gigantea against the insect Oleander aphid and on the Hibiscus rosa-sinensis against the insect Aphis fabae.
