Additional fungicides for Fusarium head blight on wheat this year - Folicur and Caramba

In Michigan, we have a lot of people to thank for helping make the Section 3 label for tebuconazole (Folicur) happen this spring. Tebuconazole, also known as Folicur, has been given a full Section 3 label by the Environmental Protection Agency for use on wheat and barley. Michigan received a state label for Folicur yesterday. We should thank Lois Rossi, Director of the Registration Division at the Office of Pesticide, Programs for EPA with her efforts to work with us to resolve the barriers that have held up registration of Folicur for the past 11 years. When told that tebuconazole would not be available for use by producers this year, the North Dakota Grain Growers Association along with regulators, researchers from NDSU, the North Dakota Ag Department, NDSU Extension Plant Pathologist Dr. Marcia McMullen, ND Pesticide Registration Coordinator Jim Gray, the National Association of Wheat Growers, Minnesota Association of Wheat Growers, University of Minnesota Extension Plant Pathologist Charla Hollingworth, Montana Grain Growers Association and the South Dakota Grain Growers Association banded together and took the initiative to make it happen.

A Section 2ee label was also granted, which allows for tank mixing of Folicur and Proline, at a rate of 3 oz each per acre. The mix of the two products actually performed better at reducing DON (vomitoxin) and controlling head scab symptoms than either product alone in multi-state Uniform Fungicide Trials sponsored by the U.S. Wheat and Barley Scab Initiative over multiple years.

Michigan also received a state label for new triazole fungicide for fusarium head blight, Caramba (metconazole) yesterday. Caramba’s performance in the Uniform Fungicide Trials has been comparable to the Proline/Folicur mix. Caramba is made by BASF. Check for product availability this season with your suppliers. Labels for both Folicur and Caramba are available in pdf format, or at MSU County Extension office or supplier.
