A field experiment was conducted to evaluation the novel insecticides against leaf folder during Kharif, 2013 & Kharif, 2014 at Crop Research Station, Masodha of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) in Rice crop. The eight treatments including untreated control were taken for experimentation. The experiment was lay out in RBD with three replication comprising Lambda cyhalothrin 5 EC @62.5g a.i/ha, Cartap Hydrochloride 4G @750g a.i/ha, Profenophos 50EC@ 500g a.i/ha, Fipronil 5 SC@ 75g a.i/ha, Imidacloprid 17.8SL @ 25g a.i/ha, Carbofuron 3 G@750g a.i/ha and Monocrotophos 36SL @ 500g a.i /ha for minimizing the incidence of leaf folder, Cnaphalcrocis medinalis (Guenee) in Rice crop. The treatment Fipronil 5 SC @75 gm a.i./ha treated plots showed lowest infestation (3.08 and 3.48%) and gave higher grain yield (40.00 and 37.7q/ha) followed by Cartap hydrochloride 4G (37.50 and 36.10 q/ha) and Carbofuron 3G (36.70 and 35.30q/ha) as compare to untreated control (25.80 and 23.30q/ha), but the highest cost-benefit ratio of (1:11.24 and 1:9.78) was obtained from Imidacloprid 17.8 SL fallowed by Cartap hydrochloride 4 G (1:7.09 and 1:7.75) and Fipronil 5 SC (1:6.04 and 1.62) respectively during 2013 and 2014.
