Charcoal rot, caused by the fungus Macrophomina phaseolina, limits yield and performance of soybean. Certain plants have been shown to produce chemicals that act as biofumigants that control harmful soil fungi. Bacterial control of diseases has been used successfully in potato production. The research will test the ability of mustard species used as cover crop to control charcoal rot in soybeans. Incorporating a cover crop into the rotation may be a simple method of controlling soil-borne diseases, and may control insects as well. The research includes an economic impact analysis. The research will develop new methods of control for charcoal rot and test fungal control methods.
