Malvick, James A. Percich. 1 computer file (PDF); ix, 204 pages, appendices A-B. Ill. (some col.)Root diseases of soybean cause substantial yield reduction in the United States. Fusarium and Phytophthora represent groups of fungal pathogens commonly associated with root rot of soybean. Little is known regarding their distribution, etiology, and how they may interact in causing root rot on soybean. Additionally, diagnostic tools that allow for rapid and accurate detection of these pathogens are essential for disease management, but need to be developed and validated. Furthermore, fungicidal compounds that potentially affect root infection by these fungal pathogens are being studied to minimize yield losses due to root diseases of soybean and improve crop productivity.en-USDetectionFusariumManagementPhytophthoraRoot rotSoybeanPlant PathologyThesis or Dissertation
