Abstract


Field experiments on Bio-efficacy of insecticides against foliar thrips (Scirtothrips dorsalis, Caliothrips indicus and Frankliniella schultzei) in summer groundnut was carried out at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh during consecutive three year i.e., 2017-18, 2018- 19 and 2019-2020. All the treatments were significantly superior over untreated check. Results of the experiment after first spray showed that the lowest thrips population per trifoliate leaf was recorded in the treatment of clothianidin 50 WDG @ 20 g a.i./ha and it was statistically at par with spinosad 45 SC @ 67.5 g a.i./ha, imidacloprid 17.8 SL @ 24.9 g a.i./ha and dinotefuran 20 SG @ 30 g a.i./ha. The treatment of Beauveria bassiana (2 x 106 cfu/g), azadirectin 0.15 EC @ 3.75 g a.i./ha were fail to reduced thrips population. Considering the pod and haulm yield on hectare base, the treatment of clothianidin 50% WDG 0.004%, spinosad 45% SC 0.014%, imidacloprid 17.8% SL 0.005% and dinotefuran 20% SG 0.006% recorded significantly the highest pod and haulm. Looking to the ICBR, treatment of imidacloprid 17.8% SL 0.005% (1:7.42) showed the highest ICBR followed by the treatment of clothianidin 50% WDG 0.004% (1: 6.24) and dinotefuran 20% SG 0.006% (1:4.16)
