abstract
Management of whitefly Bemisia tabaci Genn. was studied on gerbera under protected condition during 2016 at College of Horticulture, Mudigere, Karnataka. Among treatments evaluated for management of whitefly, diafenthiuron 50 SC, fipronil 5 SC and thiamethoxam 25 WG were found to be superior in reducing the mean whitefly adults and nymphal population after first and second foliar spray and highest C: B ratio also obtained from these treatments. They were followed by imidacloprid 17.8 SL, acetamiprid 20 SP, dimethoate 30 EC and cyantraniliprole 10 OD in recording lower whitefly population.
