The experiment was conducted at the Central Research Farm (CRF), SHUATS, Naini, Prayagraj during Rabi 2022. Seven treatments were evaluated against, Leucinodes orbonalis i.e., Emamectin benzoate 5% SG @ 0.4ml/lit (T₁) (14.34), Neem oil 5% @ 5ml/lit (T₂) (20.71), Spinosad 45% SC @ 0.5ml/lit (T₃) (12.97), Chlorantraniliprole 20% SC @ 0.5ml/lit (T₄) (9.98), Beauveria bassiana @ 2gm/lit (T₅) (17.04), Indoxacarb 14.5% SC @ 0.5ml/lit (T₆) (15.67), Metarhizium anisopliae @ 4gm/lit (T₇) (18.51). The yields among the treatments were significant. The highest yield was recorded in T₄ Chlorantraniliprole 20 SC (168 q/ha) followed by, T₃ Spinosad 45 SC (159 q/ha), T₁ Emamectin Benzoate 5 SG (136 q/ha), T₆ Indoxacarb 14.5 SC (133 q/ha), T₅ Beauveria bassiana (112 q/ha), T₇ Metarhizium anisopliae (103 q/ha), and the treatments T₂ Neem oil 5% (100 q/ha) was least effective among all the treatments. Control plot T₈ (74 q/ha) yield. When cost benefit ratio worked out, interesting result was achieved, among the treatment studied, the best and most economical treatment recorded in T₄ Chlorantraniliprole 20 SC (1:7.10) followed by, T₃ Spinosad 45 SC (1:6.47), T₁ Emamectin Benzoate 5 SG (1:6.34), T₆ Indoxacarb 14.5 SC (1:5.71), T₅ Beauveria bassiana (1:5.65), T₇ Metarhizium anisopliae (1:5.11), and the treatments T₂ Neem oil 5% (1:4.99) was least effective among all the treatments. Control plot T₈ (1:3.86) was recorded.
