| Common Bunt (Tilletia caries) is a mainly seed borne disease and causes high losses in organic wheat and spelt production. Due to the basic role of seed health in disease prevention, seed quality aspects have to be focussed strictly in organic farming.

The data indicated significantly the increasing spread of Tilletia caries in seed production in the last years, nevertheless in 2012 a high rate of more than 90% of the tested lots still corresponds to the requirements for untreated seed according to the Austrian Seed Regulations (threshold level 10 spores/kernel).
