SUMMARY The aim of this experiment was to evaluate five fungicides normaly used as seed dressing on the control of Dreschlera teres, in barley. The yield was influenced by all fungicides tested. The height of seedlings was reduced by tebuconazol and triadimenol while dry matter was significantly reduced by difenoconazol (30g i.a./100kg of seeds). The higher percentage of emergency was obtained by difenoconazol (30g i.a./100kg of seeds) and iprodione + thiram. The five fungicides reduced the pathogen incidence, the coleoptile length and root lenght.
