Evaluation of different formulations of entomopathogenic fungi against bhendi aphid, Aphis gossypii (Glover) under laboratory conditions
Oil and granular formulations of three entomopathogenic fungi viz., Beauveria bassiana, Metarhizium anisopliae and Verticilium lecanii were evaluated against the bhendi aphid, Aphis gossypii. Results showed that the dose 1×108 conidia/ml of M. anisopliae + glycerol + sunflower oil combination exhibited highest per cent mortality (73.33%) at 10 DAT in oil formulation compare to B. bassiana,+ glycerol + sunflower (60.00%) followed by V. lecanii + glycerol + sunflower (53.33%) respectively. Wherein granular formulation the same M. anisopliae at 10 g dose demonstrated highest mortality (53.33%) at 10 DAT respectively
