A study was conducted on the evaluation of efficacy of some ecofriendly insecticides for the management of common rice leaffolder (Cnaphalocrosis medinalis Guenee) under rice ecosystem of Eastern Uttar Pradesh for the two consecutive years (2014 and 2015) at farmer field of district Deoria. This evaluation was observed most effective ecofriendly insecticides concerned to lowest infestation, lowest P: D ratio, and highest yield. There were 10 treatments (09 insecticides + 01 check) evaluated under randomized block design (RBD) by transplanting method of rice cultivation on localized popular rice cultivar Samba Mahsuri. The surveillance was conducted as per methodology of agroecosystem analysis (AESA) (Pontius et al., 2002) ^[19] modified as accessibility. The common rice leaffolder is a sporadic insect pest of rice and accounted for 15-25% yield loss. It was observed most serious insect pest and confined infestation over 15% during the study. The insecticide treatments comprise 9 insecticides (Cartap Hcl, 50 SP, Indoxacarb 14.5 SC, Imidacloprid 17.8 SL, Chlorpyriphos 20 EC, Thiamethoxam 25 WG, Chlorantraniliprole 18.5 SC, Azadirachtin (Neem Oil) 0.03 EC, Bacillus thuringiensis kurstaki (Btk) 3.5 WP, and combination of Neem Oil 0.03 EC + Btk 3.5 WP). There were 3 insecticides (Cartap Hcl,, Imidacloprid and Neem Oil + Btk) inference non-significant for lowest infestation; 2 insecticides (Imidacloprid and Neem Oil + Btk) inference non-significant for lowest P:D ratio; 3 insecticides (Cartap Hcl,, Imidacloprid and Neem Oil + Btk) inference non-significant for highest yield. There were 2 insecticides (Imidacloprid and Neem Oil + Btk) inference most effective ecofriendly insecticides. Though, both the insecticides (Imidacloprid and Neem Oil + Btk) were being most effective ecofriendly insecticides, yet Neem Oil + Btk as biorationals primarily would be the best choice before Imidacloprid for the most effective ecofriendly management of common rice leaffolder.
