Compatibility of entomopathogenous fungi with commonly used insecticides for management of banana aphid transmitting banana bunchy top virus (BBTV) in Assam banana production system

The three entomopathogenic fungi viz., Beauveria bassiana (Bals.) Vuill., Metarhizium anisopliae (Metchnikoff) Sorokin and Verticillium lecanii were tested for their compatibility with three insecticides used in banana production system in in vitro by poinson food technique. All the insecticides were tested for their compatibility with each fungi at three different concentrations i.e., recommended dose (RD), half of the RD and one fourth of the RD. V. lecanii was found highly compatible with all the insecticides followed by B. bassiana.
