An evaluation was conducted on the bioefficacy of some novel insecticides for the ecofriendly management of yellow stem borer (Scirpophaga incertulus Walker) in rice crop under Eastern Uttar Pradesh conditions 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 agro ecosystem analysis (AESA) (Pontius et al., 2002) modified as accessibility. The yellow stem borer is an endemic insect pest of rice and accounted for 10-60% 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 eco-friendly insecticides. Though, both the insecticides (Imidacloprid and Neem Oil + Btk) were being most effective eco-friendly insecticides, yet Neem Oil + Btk as biorationals primarily would be the best choice before Imidacloprid for the most effective eco-friendly management of yellow stem borer of rice.
