Insecticidal Activity of Chenopodium Album Against Plutella Xylostella on Brassica Oleacera Var. Acephala.

Abstract

The present work deals with the influence of the powders, aqueous and methanolic extracts of Chenopodium album plant on survival of the Brassica oleacera moth, Plutella xylostella (Diamondback moth), as well as, the phytochemical studies of the chemical constituents present in the leaves extract of C. album. The powders tested were obtained from the roots and the leaves of the plant. The insecticidal activity was evaluated using the leaf disc immersion method. The powders of the leaves (IC 50 value 100% at 0.1 g and 0.3 g, respectively), powder of the roots (IC 50 values 77.5% at 0.1 g and 95.0% at 0.3 g), aqueous extract of the leaves (IC 50 values 50.0% at 0.1 v/v and 80.0% at 0.2 v/v), aqueous extract of the roots (IC 50 values 52.0% at 0.1 v/v and 90.0% at 0.2 v/v) and the methanolic extract of the roots (IC 50 value 72% at 0.
