Abstract

The experiment was conducted at the research field of Department of Entomology, Sam Higginbottom University of Agriculture Technology and Sciences Prayagraj, during Kharif season 2023. The experiment was laid out in a Randomized Block Design (RBD) with three replications, Eight treatments were evaluated against yellow stem borer Scirpophaga incertulas viz., Spinosad 45SC @ 0.2ml/l, Beauveria bassiana (1x108CFU/g) @1.5 g/l, Fipronil 5SC @ 2ml/l, Acephate95SG @ 682ga.i/ha, Metarhiziumanisopliae (1.15% CFU) @2000g/ha, Lamda Cyhalothrin 5EC@ 0.5ml/l, Bacillus thuringiensis (2x109 POB) @1.5g/l, and Control. Among the different chemical and biopesticides, the pooled analysis of per cent dead hearts were recorded least in Spinosad45SC which was the most effective treatment with (12.98% and 13.93%) mean dead heart percent , followed by Lamda Cyhalothrin 5EC (13.27% and 14.63%), Acephate95SG (13.58% and 15.06%) and Fipronil 5SC (14.10% and 15.29%).The next best treatments were found to be Beauveria bassiana (1x108CFU/g) (14.38% and 15.67%), Bacillus thuringiensis (2x109 POB) (14.64 and 15.94%), Metarhizium anisopliae (1.15%CFU) (14.97 and 16.19%) and the highest dead heart percent infestation of Scirpophaga incertulas (Walker) was found in Control (15.77% and 18.54%). The highest yield and cost benefit ratio was recorded from Spinosad (51.5q/hac) and (1:4.51), followed by Lamda Cyhlothrin (45q/hac) and (1:4.35), Acephate (43q/ha c) and (1:4.18).
