Abstract: The present study was conducted during kharif, 2015 at Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment was laid out in Randomized Block Design (RBD) with six treatments including untreated control replicated four times. In the insecticidal experiment, treatment flubendiamide @ 100ml/ha was most effective against defoliators pest viz; S. litura and C. acuta after first spray having minimum population of 0.29, 0.14 larva/mrl, respectively and in after second spray 0.20, 0.19 larva/ meter row length was recorded. Percent reduction of pest population was maximum with 57.97%, 75.00% after first spray and 72.97, 70.31 percent after second spray of flubendiamide @ 100ml/ha treated plots against defoliators pest S. litura and C. acuta. Triazophos @ 750 ml/ha was most effective against sucking pest viz white flies after first spray having minimum population of 5.18 white flies/plant, 3.11thrips/plant and after second spray having 3.68 white fly/plant, 1.02 thrips/plant, respectively. Percent reduction of insect population was maximum in the triazophos @ 750 ml/ha treated plots against sucking pest and thrips after first spray having 55.11%, 52.81% and after second spray with 59.82%, 79.14%, respectively.
