Impact of certain bio-pesticides on larval mortality of Helicoverpa armigera Hiibner (Noctuidae: Lepidoptera) in chickpea

摘要

Data recorded after 14th days of treatment showed that Btk (1.25 kg), HaNPV (350 LE), WaNPV (125 LE) + Btk (0.5 kg), Btk (0.5 kg) + quinalphos (0.02%) exhibited the highest mean larval mortality as 93.33%. Btk (1.25 kg) proved its highest efficacy with similar potency (93.33%) in both the years. Azadirachtin (0.05%) showed lowest mean larval mortality as 33.33%.
