Six plant products namely, neem oil (20%), neem seed kernal extract NSKE (5%), leaf extracts of Prosopis juliflora (5%), Ipomoca carnea (5%), Vitex negundo (5%) and Azadirachta indica (5%) were evaluated with a standard insecticide, carbaryl 10 D for their efficacy against sesame pod bug (SPB) incidence, pod damage and yield during Summer '96 and Kharif 96 by applying them twice at 75 and 90 days after sowing at Agricultural Research Station, Virinjipuram. The data on this experiment were subjected to pooled analysis. Among the botanicals evaluated NSKE (5%), neem oil (2%) leaf extracts of V. negundo (5%), P. juliflora (5%), Lcarnea (5%) and A.indica (5%) were effective in descending order. However NSKE and neem oil were most effective treatments in cost wise than the insecticidal check. Hence these two botanicals cant be used economically in IPM programme.
