Abstract: The present investigation entitled “Efficacy of certain insecticides against yellow stem borer, Scirpophaga incertulas (Walker) in Trans Yamuna region of Allahabad” was undertaken at the Central field SHUATS, Naini, Allahabad. The pests appeared on 35th standard week (4th week of August) on rice crop with an average infestation percent 1.35 DH% per hill on per plot. Yellow stem borer infestation increased gradually reached peak level of 6.35 DH% per hill on 41th standard week (October 2nd week). The spray was taken for the management of Yellow stem borer. The data on the Yellow stem borer infestation percent per hill of after spray revealed that all the chemical treatments were significantly superior over control. Among all the treatments lowest Yellow stem borer infestation per hill was recorded in Fipronil (1.02) followed by Monocrotophos (1.37), Spinosad (1.69), Cartap hydrochlorid (1.98), Chloropyriphos (2.15), Imidacloprid (2.44) and Acephate (3.02) as compared to control. The yields among the treatment were significant. The highest yield was recorded in Fipronil (46.3q/ha) followed by Monocrotophos (44.5q/ha), Spinosad (44.3q/ha), Cartap hydrochloride (43.3q/ha), Chloropyriphos (42.8q/ha), Imidacloprid (40.5q/ha), Acephate (39.1q/ha) as compared to Control (29.5q/ha). When benefit cost ratio was worked out, interesting result was achieved. Among the treatment studied, the best and most economical treatment was Monocrotophos (1:3.45) followed by Fipronil (1:3.43), Cartap hydrochloride (1:3.43), Spinosad (1:3.42), Chloropyriphos (1:3.36), Imidacloprid (1:3.25), Acephate (1:2.92) as compared to T8 Control (1:2.74).
