ABSTRACT

Studies were carried out to find the effects of joint action between Bacillus thuringiensis subsp. aizawai (Bta) (Agree®) and synthetic pyrethroids against third instar larvae of H. armigera on different hosts. The joint action of Bta+pyrethroids at LC25+LC25 revealed supplemental synergism as the combined application on different hosts showed 4.75-21.72 and 18.36-38.26% more than the expected mortality at LC50 of Bta alone and LC50 of pyrethroids alone, respectively.
