Abstract

Applications of Helicoverpa armigera Nuclear Polyhedrosis Virus (HaNPV), Quinalphos, Bacillus thuringiensis kurstaki (Btk) and Beauveria bassiana (B.b.) as full doses gave hundred percent larval mortality to the test insect, 2nd instar larvae of Helicoverpa armigera. Treatment combinations containing half doses of HaNPV + Btk, HaNPV + B.b., HaNPV + Quinalphos, Btk + B.b., Btk + Quinalphos, B.b.+ Quinalphos, also gave cent percent larval death. Azadirachtin as half dose of application was found to be least effective (50%). However, all the treatment combinations were found effective over the untreated control.
