Abstract
Study on mungbean yellow mosaic virus on soybean was carried out with respect to different events prior to development of epidemics due to inoculum build up in reservoir hosts. Long term surveillance study on disease flare-ups revealed that field near irrigation canals, water points, low lying areas and foot hills had high disease incidence when compared to field unirrigated plains. Soybean cv. 1S 81-335 and Corchorus olitorius L. were found to act as bridge hosts in bringing inoculum of yellow mosaic virus from mungbean to soybean. Plant species like Paracalyx scuibiosus was founded to act as reservoir host of yellow mosaic inoculum. In addition Alternornthera sessilis and Sida rhombifolia the weed hosts recorded, were found to help the multiplication and spread of inoculum Study of weather parameter on yellow mosaic virus and whitefly population revealed that the rate of disease development was high when maximum temperature and relative humidity ranged between 31.0oC - 36.2°C and 62 - 75% respectively.
