Abstract:
A field trial was conducted at Naini, Prayagraj during the kharif season 2022 at Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, (U.P.). Eight treatment including untreated control were evaluated against Scirpophaga incertulas (Walker) i.e., (T₁) Fipronil 5% SC @ 0.1 ml/lit., (T₂) Chlorantraniliprole 0.4 G @ 20 gm/lit., (T₃) Flubendiamide 480 SC @ 0.1 ml/lit., (T₄) Spinosad 45% SC @ 0.1 ml/lit., (T₅) Nisco sixer plus @ 1 ml/lit., (T₆) Metarhizium anisopliae WP @ 2 gm/lit., (T₇) Azadirachtin 10000 ppm @ 1 ml/lit and untreated control. The data on the yellow stem borer infestation percent per hill of after spray revealed that all the treatments were significantly superior over untreated control. Among all the treatments lowest yellow stem borer infestation per hill was recorded in Chlorantraniliprole 0.4 G (3.08) after first and second insecticidal spray respectively, which is followed by Spinosad 45% SC (4.04), Fipronil 5% SC (4.16), Flubendiamide 480 SC (4.47), Metarhizium anisopliae WP (4.84), Nisco sixer plus (5.13) and (5.67) as compared to untreated control. Among the entire treatment highest yield was recorded in Chlorantraniliprole 0.4 G (49.1 q/ha) followed by Spinosad 45% SC (44.1 q/ha), Fipronil 5% SC (44.8q/ha), Flubendiamide 480 SC (43.2 q/ha), Metarhizium anisopliae WP (36.1 q/ha), Nisco sixer plus (35.8q/ha), Azadirachtin 10000 ppm (34.4 q/ha) as compared to untreated control (21.7 q/ha). The best and most economical treatment was Chlorantraniliprole 0.4 G (1:2.55) followed by Spinosad 45%SC (1:2.50), Fipronil 5% SC (1:2.39), Flubendiamide 480 SC (1:2.27), Metarhizium anisopliae WP (1:2.23), Nisco sixer plus (1:2.14), Azadirachtin 10000 ppm (1:2.12) as compared to untreated control (1:1.41).
