摘要
A laboratory study was carried out to evaluate the effect of water extracts of four plant leaves in the phytophagous pest control. Various concentrations, of the extracts (0.5,1,2, 4 and 6%) were used against last instar larvae of Spodoptera litura Fabricious. Calotropis giganta was found to be the most toxic plant product followed by Vitex negundo Linn. Azadirachta indica Adr Juss. and Pongamia glabra. Use of these plant products, a natural ecofriendly products is suggested in the management of the S.litura.
