The Mycotoxin Diagnostic Laboratory has been funded by the Minnesota Small Grain Initiative (SGI) since 1994 and is one of four DON (deoxynivalenol) testing laboratories supported by the U.S. Wheat and Barley Scab Initiative (USWBSI). We provide mycotoxin analyses, especially DON, 15-Acetyl-DON (15-ADON), 3-Acetyl-DON (3-ADON) and nivalenol (NIV), for Fusarium Head Blight research projects, and can also help local growers assess mycotoxin contamination on their crops when needed.

The Soybean Pathology project focuses on managing diseases of soybean found in Minnesota. Minnesota agriculture is increasingly dependent on the productivity of two crops, corn and soybean. Together these two crops are planted on more than half of the cropping area of Minnesota. With essentially two crops grown on large areas, the disease management benefits of crop rotation are no longer available. In some instances diseases such as diseases caused by Pythium species, the pathogen infects both crops limiting plant stands and crop yields of both corn and soybean. Sudden Death Syndrome a pathogen of soybean proliferates on corn residues and infects corn plants without affecting corn yields. Fusarium root rots, particularly root rot caused by Fusarium graminearum causes both stalk rot of corn and seed and seedling rot of soybeans. Because of the limited disease management options available to farmers, I’ve emphasized identification of resistance, phenotyping for resistance, as the emphasis of research conducted on my Soybean Pathology project.
