Technical Abstract: In recent years, Bean pod mottle virus (BPMV) has emerged as a new pathogen of soybeans in Ohio along with increased populations of its vector, the bean leaf beetle. In addition, higher incidence of seed coat mottling and soybean stems that remain green after pods mature have occurred. Nine northern soybean cultivars and two germplasm lines were evaluated in a field study to determine the effects of early and late virus inoculations. Early inoculation (unifoliate growth stage) with BPMV resulted in foliar symptoms, mottled seed and reduction in plant height and yield. In contrast, there were no foliar symptoms or reductions in height or yield for soybeans inoculated with BPMV at the R6/R7 growth stage. Symptoms of green stem did not develop in this study. The results suggest that early BPMV infection produces the most agronomically important effects, and that management practices that limit virus spread at this growth stage are warranted
