Abstract:

Yellow mosaic disease (YMD) on horsegram caused by begomovirus belongs to family geminiviridae is an emerging threat for crop cultivation in peninsular India and in many parts of Karnataka. The present etiological studies indicated that the symptoms characterized by faint yellow discoloration on the young leaves in the beginning as disease progresses, the leaves show characteristic symptoms of mottling. The mottling are irregular, small, greenish yellow in colour and intermixed with normal green patches, later on the mottling become enlarged and turn bright yellow and eventually become completely bleached. The average incidence of horsegram yellow mosaic disease (HgYMD) varied from 10.68 to 44.91% in major surveyed areas of north eastern Karnataka. The maximum incidence (44.91%) was recorded in Kushtagi taluk of Karnataka. Among the 15 host plants belonging to diversified families tested for host range, blackgram (Vigna mungo), greengram (V. radiata), soybean (Glycine max), pigeon pea (Cajanus cajana), Croton bonplandianum, Parthenium hysterophorus, Malvestrunm coromandelium and Alternenthera sessile were shown to be susceptible.
