Evaluation of selected pesticidal plant extracts against diamondback moth (Plutella xylostella)

Abstract

An evaluation of methanolic extracts of Lantana camara (L.), Eupatorium adenophorum (Spreng), Artemisia brevifolia (Wall), Melia azedarach (L.) and Rumex nepalensis were studied at 1.25, 2.5 and 5.0% concentrations for their efficacy against Diamondback moth. Studies revealed that ovicidal activity was more pronounced at highest concentration tested. Out of all the plants tested Melia azedarach (5%) concentration inhibited the oviposition by Diamondback moth completely. This was followed by Eupatorium adenophorum and Artemisia brevifolia
