Abstract

The present investigation was carried out at Central Research Farm (CRF), Department of Entomology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh during Kharif season of 2023. The experiment was laid in Randomized Block Design with seven treatments replicated thrice along with untreated control plot. Eight treaments viz. Imidachloprid 17.8 SL @ 0.5ml, Neem seed kernel extract 5% @ 4ml/l, Spinosad 45 SC @ 0.3ml/lit, Neem oil 2% @ 3ml/lit, Neem oil 2% @ 3ml + Flubendiamide @ 0.4ml/lit, Indoxacarb 14.5 SC @ 1ml/lit, Flubendiamide 480 SC @ 0.4ml/lit were evaluated against shoot and fruit borer (Leucinodes orbonalis). Study revealed that all the treatments was found significantly superior over control. The result showed that the treatments lowest percent shoot and fruits, infestation was recorded in T3 Spinosad 45 SC @ 0.3ml/lit (1.87), followed by T1 Imidachloprid 17.8 SL @ 0.5ml/lit, (2.28), T7 Flubendiamide 480 SC @ 0.4m/lit (2.74), T6 Indoxacarb 14.5 SC @ 1ml/lit (3.71), T5 Neem oil 2% @ 3ml/l + flubendiamide @ 0.4ml (4.31), T2 Neem seed kernel extract 5% @ 4 ml/l (4.52) and T4 Neem oil 2% (4.77). The treatments T4 Neem oil 2% (4.77) was least effective among all the treatments against Leucinodes orbonalis. The highest yield was recorded in T3 Spinosad 45 SC (195.30 q/ha 1:8.4), followed by T1 Imidachloprid 17.8 SL (170 q/ha 1:7.9), T7 flubendiamide (145 q/ha 1:6.1), T6 Indoxacarb 14.5 % SC (130 q/ha 1:5.9), T5 Neem oil 2% + flubendiamide (120.5 q/ha 1.46), T2 Neem seed Kernel extract 5% (115.5 q/ha 1:4.4) and T4 Neem oil 2% (90.4 q/ha 1:3.9). Control plot T8 (55.14 q/ha 1:2.7) yield.
