Brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) is a monophagous and key pest in brinjal. The efficacy of entomopathogens such as Metarhizium anisopilae (Biomagic), Beauveria bassiana (Biopower), Lecanicillium lecani (Biocatch) and biopesticides (pungam oil) was evaluated against L. orbonalis under field condition on brinjal keeping flubendiamide 39.35% SC as a standard check. From the result in the field, the maximum reduction in larval population was observed in standard check i. e. flubendiamide 39.35% SC (61.85 and 63.43%) followed by Biocatch 0.3% (58.87 and 60.36%) and Biopower 0.3% (43.85 and 43.56%) during rabi 2019. Similar results were also observed during khaif 2019. The overall results obtained in both the seasons concluded that all the treatments gave significant reduction in larval
population of L. orbonalis. The most effective treatment was Biocatch 0.3% next to flubendiamide 39.35% SC which was kept as standard check against L. orbonalis in brinjal.
