Project Summary

Bean pod mottle virus is the most common virus infecting soybeans in the North Central States. The risk continues to grow based on surveys conducted in Iowa. In order to devise more cost effective integrated BPMV disease management programs, more knowledge is needed for the interaction between the host crop, the virus pathogen and environment. Row spacing has been reported to influence the micro-climate within the crop, thereby affecting the fungal and bacterial pathogens. The effect of row spacing on temporal and spatial dynamics of a plant virus that is vectored by insects, such as BPMV and the bean leaf beans, has not been investigated.

Project Objectives

1. Temporal dynamics of BPMV in soybeans planted in different row spacing.
2. Spatial spread of BPMV as affected by row width spacings.
3. Population densities of Japanese beetles under different row width spacings.
4. Develop, evaluate and compare bean leaf beetle and Japanese beetle survival models to assess winter survival and the difference in BPMV incidence in Iowa.
