Efficacy of newer insecticides against sucking pest complex in summer sesame

Experiment was undertaken during summer 2018 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh to determine the efficacy of newer insecticides against sucking pest complex in summer sesame. The results showed that treatment spinosad 45 SC @ 0.0135 per cent and fipronil 5 SC @ 0.01 per cent were found most effective for control of thrips. Treatment dinetofuran 20 SG @ 0.008 per cent, acetamiprid 20 SP @ 0.008 per cent and imidacloprid 17.8 SL @ 0.005 per cent were found most superior against jassid while the treatment diafenthiuron 50 WP @ 0.05 per cent and spiromesifen 240 SC @ 0.24 per cent were found effective in management of whitefly. The highest yield 900 kg /ha obtained from the plot treated with dinetofuran 20 SG @ 0.008 per cent which was statistically at par with fipronil 5 SC @ 0.01 per cent, diafenthiuron 50 WP @ 0.05 per cent and flonicamid 50 WG @ 0.015 per cent with 876.39 kg /ha, 861.08 kg /ha and 840.65 kg /ha respectively. Maximum yield loss could be avoided with dinetofuran 20 SG @ 0.008 per cent (90.53 %), fipronil 5 SC @ 0.01 per cent (85.53 %), diafenthiuron 50 WP @ 0.05 per cent (82.29 %) and flonicamid 50 WG @ 0.015 per cent (77.96 %).
