Abstract
An experiment of Maize stem borer Chilo partellus using different Bio-pesticides in field condition was carried out during Kharif 2022-2023 at central Research field SHUATS Prayagraj, UP., India. The management of Maize stem borer was done using 8 different treatments and benefit cost ratios of all the treatments were calculated. Total two sprays were applied to protect the crop from Chilo partellus using randomized block design with three replications. The observations of Chilo partellus 24 hours before (Pre- treatment) and 3rd, 7th and 14th day after spraying (post-treatment) were recorded for computing the percent of larval population reduction. The data were subjected to statistical analysis after appropriate transformation for interpretation. The treatment with recommended insecticide cost benefit ratio and yield is in Imidacloprid 200 SL (T7) (1:5.01) (40.49q/ha) followed by Beauveria bassiana (2 CFU×108 ml) (T1) (1:4.53) (38.45q/ha), Bacillus thuringiensis (108 CFU/ml) (T4) (1:4.41) (37.7q/ha), Metarhizium anisopliae (T2) (1:4.20) (36.79q/ha), NPV (T3) (1:4.03) (35.98q/ha), NSKE @ 5% (T5) (1:3.97) (34.6q/ha), Azadirachtin 0.03% (T6) (1:3.85) (33.57q/ha) Lest monetary return and yieldwas obtained with control (T0) (1:3.52) (28.4q/ha).
