Final Project Results

Updated September 17, 2020:
A high-glucosinolate mustard with biofumigant properties reduced the population levels in soil and in soybean plants of the fungus (Macrophomina phaseolina) that causes charcoal rot. In this study, management practices that incorporate use of mustard as a cover crop in soybean production systems were tested. Results indicate that tillage increases the charcoal rot fungus. The mustard cover crop was tested in field studies for its impact on soil
health, fungal disease and propagules, and soybean growth and yield.

This research indicates the potential for use of the mustard as a cover crop to control soil-borne disease in soybean. The mustard cover crop can significantly reduce the disease pressure. Greater improvements in disease pressure are observed for management practices that maintain the cover crop residue. More research is needed to further delineate changes in soil health parameters with mustard cover crops and management practices.
