abstract
The field experiment was under taken to evaluate the efficacy of different seven insecticides viz., emamectin benzoate 5 SG @ 0.002%, imidacloprid 17.8 SL @ 0.017%, fipronil 5 SC @ 0.01%, spinosad 45 SC @ 0.009%, azadiractin 3000 ppm @ 0.03%, NSKE @ 5% and triazophos 40 EC @ 0.08% against major insect pests of brinjal during Kharif 2018-19. The results revealed that imidacloprid 17.8 SL was most superior in minimising sucking pests i.e. jassid ((Amrasca bigutulla bigutulla Ishida) and whitefly (Bemisia tabaci Gennadius) population of 1.27 jassids/3 leaves and 1.21 whiteflies/3 leaves, respectively) and it was found at par with fipronil 5 SC (2.18 jassids and 2.07 whiteflies), spinosad 45 SC (2.41 jassids and 2.30 whiteflies) and emamectin benzoate 5 SG (2.46 jassids and 2.46 whiteflies). As regards brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) infestation, spinosad 45 SC was found highly effective with least mean per cent damaged shoots (1.60%) followed by emamectin benzoate 5 SG (1.73%), fipronil 5 SC (2.03%) and triazophos 40 EC (2.14%). While in case of fruit infestation on number and weight basis, plots treated with spinosad 45 SC was also found to be the most superior treatment shows lowest fruit damage of 12.47 and 10.69 per cent on number as well as weight basis, respectively and it was statistically at par with emamectin benzoate 5 SG @ (13.74 and 11.59%) and fipronil 5 SC (15.32 and 11.65%), respectively.
