The present investigation has been conducted in rice crop were carried out at Students' Instructional Farm, A. N. D. U. A. & T., Kumarganj, Ayodhya (U.P.) during Kharif 2021. The population of yellow stem borer, leaf folder, ear head bug, brown plant hopper, white backed plant hopper and green leaf hopper initiated after sowing till harvesting. Among the various treatments evaluated for the management of rice yellow stem borer and ear head bug, T2-Chlorpyriphos 50% + Cypermethrin 5% EC 750 ml ha⁻¹ treated plots found most effective and gave maximum yield of 31.69 q/ha followed by T3-Novaluron 5.25% + Indoxacarb 4.5% SC 750 ml ha⁻¹ treated plot with 30.09 q ha⁻¹. The maximum net return and cost: benefit ratio of Rs. 16849.20 and 1:5.16 was found in T2-Chlorpyriphos 50% + Cypermethrin 5% EC 750 ml ha⁻¹ followed by T8-Thiamethoxam 25% WG 100 g ha⁻¹ i.e., Rs. 7209.00 ha⁻¹ and 1:3.27. The efficacy of remaining treatments in order to their superiority were T1-Profenofos 40% + Cypermethrin 4% EC 1250 ml ha⁻¹ (1:4.02), T5-Acephate 70% SP 500 g ha⁻¹ (1:3.75), T3-Novaluron 5.25% + Indoxacarb 4.5% SC 750 ml ha⁻¹ (1:1.50), T7-Imidacloprid 70% WG 150 g ha⁻¹ (1:1.20), T4-Imidacloprid 40% + Ethiprol 40% WG 400 g ha⁻¹ (1:0.41) and T6-Emamectine Benzoate 5% SG 250 g ha⁻¹ (1:0.15).
