Abstract
The field experiment was carried out during Kharif season of 2023 at the Organic Research Farm Karguaji, Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University Jhansi (U.P.). Nine treatments were tested: neem oil, garlic bulb extract, Bacillus thuringiensis, karanj oil, panchgavya, neem seed kernel extract (NSKE), Beauveria bassiana, Metarhizium anisopliae, and a control, under a randomized block design. Three sprays of treatments were applied. The results showed that neem oil at 2 ml/L resulted in the minimum shoot damage (7.82%), followed by Bacillus thuringiensis at 5 gm/L and NSKE at 5 ml/L. To manage fruit infestation caused by brinjal fruit and shoot borer, Bacillus thuringiensis and neem oil were themost effective treatments, followed by Beauvaria bassiana and Metarhizium anisopliae. The maximum yield and highest cost benefit ratio were found with Bacillus thuringiensis (1:3.15), followed by Metarhizium anisopliae (1:3.07) and Beauveria bassiana (1:3.04).
