Effect of Selected Bio-pesticides and Chemicals against Brinjal Shoot and Fruit Borer, Leucinodes orbonalis (Guenee.) in Trans Yamuna Region of Prayagraj, India

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.
