Abstract
Useful plants can be protected against soil-borne and seed-borne diseases by coating the seeds of said plants with fungus spores, in particular ascospores of Chaetomium globosum, mycelium, bacteria or culture extracts thereof. The protection is in some cases superior to that afforded by sugar beet and cotton seeds which are coated with commercially available fungicides.
