Control of Yellow Mosaic Disease of Mungbean (Vigna Radiata L. Wilczek) with Chemicals and Botanicals

Abstract

ABSTRACT
Mungbean (Vigna radiata L. Wilczek) is an important pulse crop in India. It is attacked by various biotic and abiotic stresses including yellow mosaic which is responsible for heavy losses. Keeping this in view, a few important chemicals and botanicals were evaluated for their antiviral efficacy against yellow mosaic disease of mungbean under natural field conditions. Experiments were conducted in R.B.D. with seventeen treatments and three replications. Results show that with four sprays of Boerhaavia diffusa root extract (10%) had minimum incidence (26.70, 27.25%) and maximum plant height, (70.90, 72.84 cm), number of primary branches (6.32, 6.84 plant− 1), secondary branches (14.21, 14.45 plant− 1), number of pods (20.39, 21.54 plant− 1), and seed yield (12.80, 13.25 qha-1) followed by four  prays of clerodendrum aculeatum (10%), A. indica (10%), and untreated plots during 2006–07 and 2007–08, respectively (Table I).
