In two-year field trials the incidence of common bunt in winter wheat was strongly reduced by seed treatment with skim milk powder (untreated seeds: 73 diseased ears per square m; treated seeds 3 diseased ears per square m). At a high infection level warm water treatment at 45 deg C, 2 hours, was less efficient than the chemical Panoctine DL (18.9 % Guazatine + 2.36 % Difenoconazol, 300 ml/100kg seed) and the skim milk powder seed treatment. However, at a low infection level the warm water treatment of wheat seeds is an alternative to the chemical dressing. The warm water treatment had no damaging effect on germination. Regarding the skim milk powder treatment, future studies on seed germination and field emergence for the main wheat cultivars grown in Switzerland as well as on the application technique are needed. Skim milk powder and warm water treatment should be applied only to certified seed of cultivars with low or medium susceptibility to common bunt
