Abstract:
A field experiment was conducted during kharif 2022 at Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh India. The experiment was conducted in Randomized Block Design with eight treatments and replicated thrice viz., Chlorantraniliprole18.5% EC (T₁), Emamectin benzoate 5% SG (T₂), Spinosad 45% SC(T₃), Spinetoram 11.7% SC (T₄), Nisco sixer plus (T₅), Azadirachtin 0.1% EC (T₆), Metarhizium anisopliae (1 x 10⁸) CFU (T₇) and control plot (T₈). Results revealed that among the different treatments Spinetoram 11.7% SC (1.889) proved to be the most effective treatment followed by Emamectin benzoate @ 5% SG (2.045), Chlorantraniliprole 18.5%EC (2.300), Spinosad 45% SC (2.456), Nisco Sixer plus (2.834), Metarhizium anisopliae (1 x 10⁸) CFU (3.600), whereas Azadirachtin 0.1% EC (4.100) was found to be least effective against this pest. Among all the treatments, the cost benefit ratio has been analyzed, in which the highest was Spinetoram 11.7% SC (1:2.74) and marketable yield (42.4 q/ha) followed by Emamectin benzoate 5% SG (1:2.53 and 38.50 q/ha), Chlorantraniliprole 18.5% EC (1:2.07 and 34.20 q/ha), Spinosad 45% SC (1:1.94 and 31 q/ha), Nisco Sixer plus (1:1.65 and 28.30 q/ha), Metarhizium anisopliae (1 x 10⁸) CFU (1:1.56 and 26.10 q/ha) and the lowest was Azadirachtin 0.1% EC (1:1.51 and 24.4 q/ha) have been recorded.
