Year: 2023
Type: article
Abstract: 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.
