Insecticidal properties of solvent extracts of Andrographis paniculata against the Diamondback moth, Plutella xylostella

Abstract

Diamondback moth, Plutella xylostella (Linnaeus.) is a key pest on Brassicaceae crops causing severe yield loss worldwide. Insecticidal properties of the solvent extracts of Andrographis paniculata against diamondback moth were studied as an alternative to insecticides. Among the extracts tested, cent per cent mortality was observed in hexane extract of A. paniculata at 0.6 per cent concentration. Maximum of 65.00 and 90.00 per cent mortality was observed in ethanol and ethyl acetate extract at 0.6 per cent concentration respectively.
