Bean pod mottle virus (BPMV) is a new soybean disease problem in the Midwest. The primary vector of BPMV is the bean leaf beetle, Cerotoma trifurcata Forster. Bean pod mottle virus causes reductions in soybean yield and seed quality. Current management strategies for this disease rely on insecticide applications for control of the vector. This study was performed during the summers of 2000–2002. Four planting dates from mid-March to mid-June were evaluated in relation to BPMV incidence and soybean yield and quality. In 2000, soybeans planted in early May produced the highest yield and the lowest percentage of discolored seeds. In 2001 there were no significant differences in yield or seed quality by planting date. In 2000 and 2001 there were no differences detected in BPMV incidence at the end of the season. All planting dates had virus incidences ranging from 70–100%. In 2002, the experiment was repeated and virus assays were performed earlier in the season.
