Induced systemic resistance of seed bacterized mung bean (Vigna radiata Wilczek) plants against aphid, Aphis craccivora Koch (Homoptera: Aphididae).
Field experiments on mung bean cv. PDM-93-11 were conducted in West Bengal, India, during the 2002/03 and 2003/04 pre- and post-kharif seasons, to explore the entomopathogenic activity of Bacillus subtilis against Aphis craccivora. Among the 11 B. subtilis strains evaluated, 9 showed the ability to promote the growth of mung bean. Two strains, including one local isolate, showed promising results by rendering resistance against A. craccivora, inducing biochemical changes in mung bean by enhancing the phenol and peroxidase concentrations. These 2 strains can be utilized in future management programmes of aphid against pulses and to open a scope for further research on B. subtilis.
