A field trial was carried out comprising of sorghum hybrid CSH-16 to evaluate the bioefficacy of spinosad 45SC (0.1ml/l), cypermethrin 10EC (0.5ml/l), novaluran 10EC(1ml/l), azardirachtin 5% and Bacillus thringiensis (1ml/l) insecticides against earhead caterpillar Helicoverpa armigera in sorghum. spinosad 45SC (0.1ml/l), novaluran 10EC(1ml/l) and azardirachtin 5% emerged as superior by recording 72.0, 66.0 and 63.0% population reduction producing a grain loss of 43.46, 42.23 and 41.16 q/ha, respectively.
