Abstract: Groundnut, a predominant oilseed crop is prevalently attacked by sucking pests contributing to a greater yield loss in Odisha. To mitigate this problem, a field investigation has been carried out in OUAT by the combination of seed treatment and insecto-acaricides against major sucking pests of groundnut. Imidacloprid 600FS@10ml/kg was used for seed treatment and chemicals such as Diafenthiuron 50%WP@600g/ha, Spiromesifen 22.9%SC@400ml/ha, Chlorfenapyr 10% SC@1000ml/ha-1, Fenpyroximate 5% EC@1000ml/ha, Pyriproxifen 10% EC @500ml/ha and Hexythiazox 5.4%EC @500ml/ha were applied as foliar spray on 30 and 45 days after sowing. The treatment comprising of Seed treatment with Imidacloprid 600FS@10ml/kg of seeds followed by two foliar spray applications of Diafenthiuron 50%WP@600g/ha recorded a significantly lower population of 0.93 thrips/leaf, 0.80 whiteflies/leaf, 1.00 jassids/leaf, 0.91 aphids/leaf and 0.41 red spider mites/leaf. This treatment was also found relatively safer to natural enemies and it produced the highest yield of 3.40 tonnes/ha with an ICBR ratio of 1:4.94.
