Management of whitefly, Bemisia tabaci Gennadius in mungbean (Vigna radiata L.)

Abstract

A field experiment was conducted on mungbean crop to evaluate different biopesticides against whitefly, Bemisia tabaci during Kharif season of 2018. The results indicated that minimum whitefly adult populations was recorded in treatment where NSKE 5% Aqueous Extract was sprayed twice (First spray : 13.6 whitefly adult/plant at 3 days after spray (DAS); Second spray : 4.13 and 4.00 adults/plant at 3 and 7DAS, respectively). Whereas, maximum grain yield (259.26 kg/ha) was obtained in treatment where NSKE 5% Methanolic extract was sprayed twice.
