Abstract:
Five biorational insecticides viz., Azadiractina 1% (1000ppm) Neem oil, Beauveria bassiana 1% WP, Bacillus thuringiensis var kurstaki 5% WP, Metarhizium anisopliae 1.0% WP and NSKE were tested against Shoot and fruit borer (Leucinodes orbonalis Guenee) larvae on brinjal. The two-year experiment was conducted during Rabi 2018-19 and 2019-20 at the Rehti Farm of school of agriculture, Mhow, BRAUSS, (MP). The efficacy of these biopesticides was recorded in terms of percent shoot damage, percent shoot drooping and percent fruit damage. At the end of two sprays in respective years, the results proved that the microbial pesticides viz., B. thuringiensis var kurstaki 5% WP, B. bassiana 1% WP, M. anisopliae 1% WP were the best. The results recorded for the percent shoot damage showed B. thuringiensis var kurstaki 5% WP (9.5%), B. bassiana 1% WP (8.83%), M. anisopliae 1% WP (9.50%) in 2018-19 and during 2019-20, B. thuringiensis var kurstakii5% WP (8.17%), B. bassiana 1% WP (10.50%), M. anisopliae 1% WP (10.67%). The percent shoot drooping showed that B. thuringiensis var kurstakii5% WP (25.28%), Beauveria bassiana 1% WP (35.57%), M. anisopliae 1% WP (37.72%) in 2018-19 and during 2019-20, B. thuringiensis var kurstakii 5% WP (27.06%), B. bassiana 1% WP (36.62%), M. anisopliae 1% WP (37.06%). The percent fruit damage recorded lowest in B. thuringiensis var kurstakii5% WP (5.94%), B. bassiana 1% WP (10.87%), M. anisopliae 1% WP (13%) in 2018-19 and during 2019-20, B. thuringiensis var kurstakii 5% WP (6.82%), B. bassiana 1% WP (10.35%), M. anisopliae 1% WP (12.15%).
