Crop plants are often infected with multiple pathogens and damaged by root feeding nematodes and herbivorous insects. The combined effects can lead to severe losses in yield. We surveyed soybean crops in Alabama for infection by plant viruses and the reniform nematode. Bean pod mottle virus (BPMV) incidence was high and appeared regional within the state. Soybean mosaic virus (SMV) was not detected in Alabama until 2009 with incidence appearing to increase but, like BPMV, is regionally located. In contrast, reniform nematode was distributed throughout the state. As BPMV and SMV incidence increase, being spread by its beetle (BPMV) or aphid vectors (SMV), yield losses due to the combined...
