Summary
With the aim to evaluate the effectiveness of techniques and measures for control of cereal bunts and smuts in organic farming systems, field trials were carried out in multiple locations from 2004 to 2006. The relevant fungal diseases included in the trials were common bunt (Tilletia tritici), dwarf bunt (T. controversa), loose smut (Usti-lago tritici, U. nuda), covered smut (U. hordei) and black loose smut (U. avenae). The following treatments were found to be effective. Common bunt: different physical methods, Tillecur, acetic acid. Loose smut of barley and wheat: warm and hot water treatment, seed treatment with ethanol (more trials needed). Covered smut of barley: warm water treatment, ethanol, Lebermooser. Loose smut of oats: hot water treat-ment, ethanol. Field resistant varieties are available (although in some cases only in limited number) for common bunt, loose smut of wheat and barley and covered smut. The status of varietal resistance against dwarf bunt is only insufficiently known. In case of black loose smut research on resistant varieties is currently being conducted.
