Custar apple seed powder as an effective alternatove for chemical pesticide

Abstract

Botanical pesticides are gaining importance as alternatives to synthetic insecticides in crop protection. Custard apple seed extract (CASE) contains bioactive compounds that demonstrate insecticidal activity. This study evaluated the efficacy of CASE against Myzus persicae (green peach aphid) and Plutella xylostella (diamondback moth) under laboratory conditions. CASE was tested at four concentrations (3%, 5%, 10%, and 100%), and mortality was assessed at 24 and 72 hours after treatment. Results showed a clear dose-dependent mortality response, with complete mortality of M. persicae at 100% concentration and P. xylostella at 10% within 72 hours. These findings highlight the potential of CASE as a promising botanical insecticide for incorporation into integrated pest management (IPM) programs.
