Evaluation of Different Insecticides against Asphondylia sesami Felt. on Sesamum

An experiment was carried out to evaluate different insecticides against Asphondylia sesami. The results revealed that on the basis of average per cent infestation of gall fly, treatments with spinosad 45 SC (0.01%) followed by thiacloprid 48 SC (0.009%) and fenvalerate 20 EC (0.01%) were foundto be most effective respectively. As regardsto the sesamum yield, spinosad 45 SC, indoxacarb 14.5 SC and fenvalerate 20 EC, were found to be most effective treatments recording yield of 737, 663 and 636 kg/ha respectively. As far as economics of the treatments is concerned, fenvalerate 20 EC, thiacloprid 48 SC and spinosad 45 SC were emerged as most economic treatments recordedanICBR of 1:11.91, 1:4.14 and 1:2.64 respectively. However, fenvalerate 20 EC was found effective in recording minimum per cent infestation of gall fly and and recorded highest ICBR of 1:11.91.
