Evaluation of different pest management modules against major insect pests of pearl millet

Abstract

A field experiment was conducted for the management of major insect pests in pearl millet during kharif 2016-18 at Millet Research station, Junagadh Agriculture University, Jamnagar. Results showed that module-IV (seed treatment of imidacloprid 600 FS @ 8.75 ml/kg at the time of sowing, removal of shoot fly dead hearts, installation of fish meal traps @ 10/ha and spraying of dimethoate 30EC @ 0.03% at 35 days after germination was found effective against shoot fly. Whereas, module-II (seed treatment of imidacloprid 600 FS @ 8.75 ml/kg + removal of shoot fly dead hearts + fish meal trap @ 10/ha + spraying of novaluron 10 EC @ 0.01%, at 35 DAG) recorded lowest stem borer per cent incidence and Helicoverpa larval population at ear head stage of crop. But, looking to the cost of management, highest additional income (Rs. 20610/-), net return (Rs. 18961/-) and ICBR (1:12.50) was recorded in module-IV (Seed treatment of imidacloprid 600 FS @ 8.75 ml/kg + removal of shoot fly dead hearts + fish meal trap @ 10/ha + spraying of dimethoate 30 EC 0.03 % at 35 DAG).
