Abstract:
The Central Research Farm (CRF) is where the current investigation was carried out, Department of Entomology, SHUATS, Prayagraj during Rabi season 2021-22. In the Randomised Block Design, there were eight treatments, including an untreated control, and each was replicated three times. Eight treatments viz, Cypermethrin 25% EC, Spinosad @ 45% SC, Neem oil @ 2%, Karanj oil @ 2%, Chlorantraniliprole 18.5% SC, Datura leaf extract @ 5%, Fipronil 5% SC, one untreated plot was taken. The observation on overall larval population of P. xylostella on cabbage. This demonstrates that each treatment was vastly superior to the control. Chlorantraniliprole 18.5% SC (01.42) found superior followed by Spinosad 45% SC (01.65), Cypermethrin 25% EC (02.02), Fipronil 5% SC (02.17), Neem oil @ 2% (02.36), Karanj oil @ 2% (02.60), Datura leaf extract @ 5% (02.81) as compared to control control (03.83). The results were quite interesting. This shows that each treatment was significantly better than the control. Chlorantraniliprole 18.5% SC (270.80 q/ha) (1:6.19), followed by Spinosad 45 SC (238.15 q/ha) (1:5.51), Cypermethrin 25% EC (220 q/ha) (1:5.46), Fipronil 5% SC (205 q/ha) (1:5.10), Neem oil @ 5% (170 q/ha) (1:4.0), Karanj oil @ 5% (165 q/ha) (1:4.0), Datura leaf extract @2% (135 q/ha) (1:3.40) vs the control (115 q/ha) (1:2.62).
