Identification of cover crops for use in biocontrol of soil-borne diseases and development of guidelines for economical use of cover crops will assist producers in controlling fungal diseases in soybean. The impact of fungicide use on yield and net return will be determined, and guidelines developed. The interaction between soil health and fungal pressure will be assessed and alternative methods of improving soil health for optimal soybean production, yield components, and net return developed. The economic impact of management choices will assist producers in choosing economically viable production systems.
This research is a component of a research project exploring the mechanisms defining how soil health impacts crop production and plant disease. The research team has developed a proposal to leverage KSC funding with national funding through USDA-NIFA. The research is exploring the interactions between soil health and crop performance, developing alternative methods to control crop diseases and establish naturally disease-suppressive soils through cultural practices.
This research will also contribute to a study examining the potential for cover crops to control the soil-borne fungus Fusarium virguiliforme that causes sudden death syndrome, in collaboration with another Kansas Soybean Commission funded project (C. Little). Overall soil health and nutrient status will be measured in collaboration with Dr. Dorivar Ruiz Diaz.
