Abstract: Rhizoctonia solani causes various diseases in many crops world wide, it also causes losses in sugar beet grown in Poland and the Netherlands. In this research three isolates of R. solani was tested, two AG5 and one AG4. They differed in pathogenic activity in field and laboratory tests. The AG5 isolates were weak pathogenic but caused the decrease of cotyledons and first pair of leaves dimension. The AG4 isolate caused totally pre-emergence damping-off and its activity was the result of mycelium colonization ability and fungus metabolites activity.
