The effect of a nicotinoid, nicotine cyanurate extracted from tobacco waste dust and an Insect Growth Regulator (IGR) diflubenzuron is reported herein against a most devastating enemy of rice, the yellow stemborer, Schoenobius incertulas (Walker) and the results are compared with that reported in the literature to seek a better control strategy for the pest. The mortality increased with the increase in dose. At higher doses in diflubenzuron molting did not occur. LD50 of diflubenzuron and nicotine cyanurate was found to be 250 and 80 µg/larva, respectively.
