The experiment on the Bioefficacy of Thiamethoxam 12.6% + Lambda cyhalohthrin 9.5% ZC @ 125, 150, 175 and 350 ml/ha along with Thiamethoxam 25%@ 100 gm/ha, Lambda cyhalohthrin 5% EC@ 500 ml/ha, Thiodicarb 75% WP@ 750 gm/ha and Quinalphos 25% EC@ 1500 ml/ha against pests in Blackgram was conducted in Randomized Block Design with three replications at Agronomy farm, R.C.A., Udaipur during , 2017 and 2018. Blackgram variety PU-31 was sown during both cropping seasons. It was evaluated that Thiamethoxam 12.6% + Lambda cyhalohthrin 9.5% ZC @ 175 ml/ha followed by Thiamethoxam 12.6% + Lambda cyhalohthrin 9.5% ZC @ 150 ml/ha was most effective to control insect pest i.e. spp., and in blackgram with highest yield production compare to other treatments. The other treatments also found significantly effective in reducing the larval population in Black gram.
