Seed treatment ofroot parsley was done to protect Petroselinum santivum seedlings against damping off. Fungicides used as seed dressers were applied in 3 doses: 3, 5 and 10 g/kg. Seeds were treated with 7 dressers (Table l) used separately and in mixture with 3 g/kg of Rovral 50 WP (50% iprodione) and 1 g/kg of Apron 35 SD (35% metalaxyl). Two seed samples of Berlińska cultivar were used: first sample was strongly infected by Alternaria petroselini and A.radicina both 27,6% and also by Fusarium spp. 5,4% (Test I), and second sample revealed lower percentage of infection 4,6% and 1,2%, respectively (Test II). The experiments were conducted under laboratory, glasshouse and field conditions. Complete seedlings protection in all experiments was achieved for treatments when fungicide mixture was used in the highest dose (10 g/kg). Decrease of fungicides concentrations were connected with lower effectiveness of disease control. No phytotoxic effects of the tested fungicide mixtures were observed under the glasshouse or field conditions
