Evaluation of some insecticidal spray sequences either alone or in combination with insect growth regulators against chickpea pod borer

The results of the experiment revealed that application of two sprays (first at 50% flowering and second at 15 days later) with methomyl 24L@ 2.0 ml/Iit., methomyl 24L@ 1.5 ml/lit., diflubcnzuron 25WP @0.8 g/lit and teflubenzuron 15SC @0.66 ml/lit gave more than 50 per cent protection against pod borer compared to untreated control. However, highest grain yield of 14.43 q/ha was recorded by carbaryl 50WP @ 2 g/lit + teflubenzuron 15SC @ 0.66 ml/lit with 62.87 per cent increased yield, followed by two sprays of endosulfan 35EC @1.0 ml/lit + teflubenzuron 15SC @ 0.66 ml/lit (13.19 q/ha), methomyl 24L @1.5ml/lit(12.97 q/ha), methomyl 24L @ 2.00 ml/lit (12.86 q/ha) and carbaryl 50WP @ 2 g/lit+ diflubenzuron 25WP @ 0.8 g/lit (12.75 q/ha) with 48.87, 46.39, 45.15 and 43.91 per cent increased yield over untreated control.
