Abstract
Virus incidence and distribution data show that the source of groundnut mottle virus for soybean is infected groundnut. The source of virus in groundnut is infected seed [RPP 53, 3706]. The virus is transmitted from groundnut to soybean, from soybean to soybean, and from soybean to groundnut. It can move at least 48 m in a single step to previously uninfected plants but apparently not 6.5 km. As the distance between inoculum source and adjacent plantings increases, the time until initial infection increases, resulting in a lower percentage of disease at crop maturity. The rapid increase of this disease in a planting was the result of inoculum dissemination from within, as opposed to between, plantings. It is this internal spread that leads to epiphytotic conditions.
