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 laboratory is equipped with two Shimadzu GC-MS instruments (GCMS-QP2010 and GCMS-QP2010 plus) purchased in 2002 and 2007, respectively. Last fall, with additional funding from the USWBSI, we purchased the newest model of Shimadzu GC-MS instrument (GCMS-QP2020) to replace the 16 years old GCMS-QP2010. The new instrument was installed in January, and has been providing faster analysis speed due to a better heat ventilation system. Currently, we have four undergraduate students, Autumn Boxum (Environmental Sciences Policy & Management), Yuning Xu (Environmental Sciences Policy & Management), Ivy Lin (Biological Sciences) and Heidi Schlinsog (Food Systems) plus Anita Jurevica (Researcher 2) and Yanhong Dong (Research Assistant Professor) working on the “Diagnostic services for DON” and “Evaluation of Small Grains Cereals for Multiple Disease Resistance and Mycotoxins” projects.
