The effect of three commonly available botanical extracts and two insecticides with different concentrations was determined in the field against yellow stem borer, Scirpophaga incertulas. The treatments include three botanical extracts viz., Tobacco extracts, Neem extracts, and Karonja extracts at 15ml/L concentration and two insecticides named Acephate 75 SP at 2g/L and Fipronil (Nema 50 SC) at 2 ml/L. The botanicals and chemicals caused a significant difference in their effect against the rice pest, S. incertulas. Maximum number of dead hearts and white heads were recorded in control plot. A highly significant result was observed in Fipronil treatment after 21 days of spraying which showed the reduction of 51.89% dead heart and 65.05% white head over control. Neem extracts reduced dead heart and white head by 38.38% and 58.08% respectively. Considering the efficacy and eco-friendly nature of Neem extract it could be considered as an effective botanical in successful management of the pest yellow rice stem borer, S. incertulas.
