Investigation on determination of economic threshold level of pearl millet stem borer, Chilo partellus (Swinhoe) carried out at Millet Research Station, Jamnagar during kharif 2017 and 2021. All the treatments recorded significant reduction of stem borer infestation than untreated control. The lowest infestation of stem borer was recorded where fully plant protection was given. 5 % plant damage recorded highest net return (Rs. 14257/-) and ICBR (1:9.15) among all the treatments. So, this treatment was found economical and should be considered as economic threshold level for the pearl millet stem borer
