The present paper discuses the feasibility of ergot contaminants control in rye seeds through seed dressing. The objective of the work was to determinate the impact of chemical and biological seed dressing on sclerotia germination and ascocarps formation. Germination (%) of sclerotia treated with most of the investigated fungicidal action chemical seed dressers was significantly lower than that of untreated sclerotia. Although some chemical seed dressers did not give very good control of sclerotia germination, they delayed ascocarps emergence and significantly reduced their number above the soil surface at rye anthesis. Biocontrol agents did not have any significant effect on sclerotia germination and ascocarps formation.
