ABSTRACT
A field study was conducted at C Unit Farm, Kalyani, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal to determine the bio-efficacy of insecticides against sucking insect pests viz., thrips (Scirtothrips dorsalis Hood), mite (Polyphagotarsonemus latus Banks) and aphid (Aphis gossypii Glover) in chilli variety bullet during kharif season of 2019. Total seven treatments viz., Flonicamid 50% WG @ 60 g a.i. ha-1, Dimethoate 30% EC@ 300 g a.i. ha-1, Fipronil 5% SC @ 50 g a.i. ha-1, Diafenthiuron 50% WP @ 300 g a.i. ha-1, Propargite 57% EC @ 850 g a.i. ha-1, Spiromesifen 22.9% SC @ 96 g a.i. ha-1 including control were considered. Among the different insecticides, Propargite 57% EC @ 850 g a.i. ha-1 against mite (75.24%), Fipronil 5% SC @ 50 g a.i. ha-1 against thrips (59.43%) and Flonicamid 50% WG @ 60 g a.i. ha-1 against aphid (55.45%) population were recorded as the most effective treatments. Highest green chilli fruit yield (30.20 quintal per hectare) was harvested from crop treated with Diafenthiuron 50% WP @ 300 g a.i. ha -1.
