Studies on the bio-efficacy of newer insecticides against sucking insect pests and fruit borer of tomato

The present study entitled “Studies on the bio-efficacy of newer insecticides against sucking insect pests and fruit borer of tomato” was carried out at the Research cum Instructional farm, Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur (C.G.). during Rabi 2024-25. The present investigation was carried out against sucking pest (whitefly, thrips and aphid) and fruit borer on tomato variety Kaveri-143 to evaluate the bio-efficacy of newer insecticides viz. Spiromesifen 22.90% SC, Flubendiamide 39.35% SC w/w, Novaluron 10%EC, Pongamia soap, Insecticides were applied twice at 10 days interval. Most effective treatment was Flubendiamide 39.35% SC w/w @ 100 ml/ha against the management of fruit borer, followed by Novaluron 10% EC @ 750 ml/ha, Pongamia soap @ 5000ml/ha and Spiromesifen 22.90% SC @ 625 ml/ha. For sucking pest most effective treatment was Spiromesifen 22.90% SC @ 625 ml/ha followed by Pongamia soap @ 5000ml/ha, Novaluron 10% EC @ 750 ml/ha and Flubendiamide 39.35% SC w/w @ 100 ml/ha. All the above treatments were found to be superior over control. The highest net profit and cost benefit ratio was observed from the plot treated with Pongamia soap (Rs 1800/ha and 1:2.02). The maximum fruit yield of 307.03q/ha was recorded with the application of Pongamia soap which was 61.38% higher than control.
