SEASONAL ABUNDANCE AND EFFECT OF INSECTICIDES AGAINST PESTS OF CHILLI

The experiment was conducted at Experimental Research Farm, Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during the Kharif season of the year 2016-17 to study population dynamics and bio-efficacy of new insecticides against insect pests of chilli. The experiment was laid out in a randomized block design with 9 treatments replicated three times. The treatments comprised of fipronil 5 SC @ 1000 ml/ha, hexythiaziox 5.45EC @ 500 ml/ha, spinosad 45 SC @ 187.5 ml/ha, acetamiprid 20 SP @ 250 g/ha, fenpyroximate 5 EC @ 600 ml/ha, emamectin benzoate 5 SG @ 250 g/ha, spiromesifen 22.9 SC @ 250 ml/ha, diafenthiuron 50 WP @ 625 g/ha and untreated control. The observations on population dynamics of thrips, mites, white fly and fruit borer also recorded.The overall results indicated that the treatment with spinosad 45 SC @ 187.5 ml/ha was found superior in controlling chilli thrips & fruit borer, whereas the treatment with diafenthiuron 50 WP @ 625 g/ha was found superior in controlling chilli whitefly, Fenpyroximate 5 EC @ 65 EC @ 600 ml/ha was found superior in controlling chilli mites.
