Abstract
A field experiment was conducted during the kharif season of 2018 and 2019 at Crop Research station, Masodha, Ayodhya to evaluate the efficacy of insecticides against rice stem borer and leaf folder. The experiment was comprising five treatments i.e. T1- Dinotefuran @ 200 ml/ha., T2- Rynaxypyr @ 150ml/ha.,T3- Cartap hydrochloride 50% SC@ 200ml/ha., T4- Triflumezopyrim 10% SC @ 48g/ha and T5- Untreated control. The lowest incidence of rice stem borer dead heart % 3.92 (30 DAT), 5.18 (50 DAT) and white ear 2.4% and incidence of leaf folder % 3.99 (30 DAT), 2.74 (50 DAT) were recorded in treatment with T4-Triflumezopyrim 10% SC @48g/ha. In both years. The highest grain yield (4305 kg/ha), yield Increase (45.19%) net return (Rs. 118388/ha) and Incremental Benefit: Cost ratio 2.46%, followed by application of Rynaxypyr @ 150ml/ha. incidence of rice stem borer dead heart % were recorded 5.52 (30 DAT), 9.80 (50 DAT) and white ear 4.11% and incidence of leaf folder % 5.59 (30 DAT), 4.31 (50 DAT) and yield kg/ha was 4104 and percentage increase of yield 38.31.
