The field experiments on efficacy of some biopesticides against H. armigera on pigeonpea under field condition was carried out in the experimental field of department of Entomology at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) Hyderabad, during 2016-2017 and 2017-2018. These studies revealed Spinosad 45 SC treatment as the most effective against H. armigera. Lower larval population of H. armigera was observed when crop was treated with consortia of biopesticides which was at par with neem fruit powder followed by HaNPV. The treatment of Spinosad 45 SC was found significantly superior, recording lower pod and seed damage by H. armigera (6.82%) followed by consortia (37.95%) and neem fruit powder (39.77%). The highest yield was (1359 kg/ha) recorded in Spinosad 45 SC followed by Streptomyces sp. (SAI-25) (762 kg/ha).
