A field experiment was carried out to evaluate eleven insecticides against Helicoverpa armigera on wheat. The results on the relative efficacy of different treatments against Helicoverpa armigera after two sprays showed that all the treatments were significantly superior over untreated control. Minimum H. armigera larval population was recorded in the treatment with spinosad 73g a.i./ha (0.02 larva/ ear head), however, it was at par with bifenthrin 80g a.i./ha (0.06 larva/ ear head) and flubendiamide 50g a.i./ha (0.10 larva/ ear head).
