Abstract:
The experiment was conducted to found out the bio-efficacy of insecticides against sucking insect pests viz., thrips (Scirtothrips dorsalis Hood), whitefly (Bemisia tabaci Gennadius) and mite (Polyphagotarsonemus latus Banks) in chilli. Among the different insecticides combination, Etofenprox 6% + Diafenthiuron 25% WG @ of 1250 g/ ha proved most effective in reducing sucking pest population and found minimum population after third spray (1.22 & 1.47 thrips, 1.30 & 1.37 whitefly and 0.40 & 0.55 mites/ 3 leaves) at 5 & 10 days after spray, respectively followed by Etofenprox 6% + Diafenthiuron 25% WG @ of 1000 g/ha in case of thrips and whitefly, while Propargite 57% EC @ 1500 ml/ha against mite and these were also statistically at par on both duration in all spray. Highest red chilli fruit yield (13.61 q/ha) was harvested from crop treated with Etofenprox 6% + Diafenthiuron 25% WG @ of 1250 g/ ha followed by Diafenthiuron 50% WP @ 600 g/ha and Etofenprox 6% + Diafenthiuron 25% WG @ 1000 g/ha.
