Abstract
Gorakhpur University, Gorakhpur, Uttar Pradesh in the season of Kharif 2023-2024 to evaluate the bio-efficacy of different insecticides against brown plant hopper (Nilaparvata lugens) on paddy crop.The Swarna variety was grown for the experiment using the RBD experimental design.Various insecticides, such as T1 Imidacloprid 17.8 SL, T2 Acetamiprid 20% SP, T3 Metarhizium anisopliae 4.7108 C.F.U./g, and T4 Thiamethoxam 25%WG, were evaluated against BPH.T5 NSKE 5% and T6 Neem oil 2% were also included in the evaluation.The experiment result revealed that imidacloprid 17.8 SL (5.95 BPH/ 10 hills) was found to most effective treatment against the brown plant hopper and significantly decreasing population of hopper followed by thiamethoxam 25%WG (6.32 BPH/ 10 hills), acetamiprid 20% SP (6.51 BPH/ 10 hills), M. anisopliae 4.7108 C.F.U./g (6.96 BPH/ 10 hills), and neem oil 2% (7.49BPH/ 10 hills).The least effective treatment found was the NSKE 5% (7.84 BPH/ 10 hills).All the treatments significantly reduced the population of brown plant hoppers compared to the control (14.58 BPH/ 10 hills).The plot treated with imidacloprid 17.8 SL had the highest paddy grain yield at 66.34 q/ha, followed by thiamethoxam 25%WG at 55.86 q/ha.The plot treated with imidacloprid 17.8 SL also showed the highest percentage increase in yield over the control at 68.70%.The highest ICBR was observed from the imidacloprid 17.8 SL (1:3.46) and the lowest ICBR was recorded in NSKE 5% (1:1.02) it may be due to its market price and effectiveness of insecticides.
