Abstract:
Field experiment for two consecutive years was taken for management of Girdle beetle (Oberopsis brevis) through microbial pesticides in soybean var. JS-335. Four entomopathogenic fungi viz. Beauveria bassiana @ 5, 4 and 3 g/l, Nomuraea rileyi @ 6, 5 and 4 g/l, Metarhizium anisopliae 5, 4 and 3 g/l and Bacillus thuringiensis @ 3, 2 and 1 g/l along with water spray as control tested at 20 DAE and thereafter two consecutive sprays at an interval of 15 days. Two years pooled data obtained recorded the superiority of treatment B. bassiana 5 g/l which cause less per cent damage (17.83). Lower dose of M. anisopliae causes high per cent plant damage after 14 DAS. The highest seed yield was obtained in the treatment, B. bassiana 5 g/l followed by B. bassiana 4 g/l and M. anisopliae 5 g/l, M. anisopliae 4 g/l.
