Abstract

In response to the growing demand for sustainable agricultural practices, this study explores the development of a botanical-based biopesticide for managing Diamondback Moth (Plutella xylostella) infestations in Cabbage (Brassica oleracea). The biopesticide is formulated using extracts from Nirgundi (Vitex negundo) and Chakramardha (Cassia tora) plants. Employing a randomized block control design, various concentrations of the biopesticide were evaluated for efficacy. Results demonstrate concentration-dependent mortality of Diamondback Moth larvae, with the highest concentration yielding the most significant effect. Damage assessment of cabbage leaves aligned with mortality trends, while prolonged protection was observed at higher concentrations. This biopesticide exhibits promising potential as an eco-friendly alternative for cruciferous crop pest management. Further research should delve into its mode of action, non-target effects, and commercial viability.
