Popis:	Six multinucleate and two binucleate strains of Rhizoctonia spp. pathogenic to the weed leafy spurge (Euphorbia esula) were compared in aggressiveness. Pathogenicity was tested by inoculating stems of leafy spurge or planting roots or seeds in soil infested with Rhizoctonia strains (8 cfu/g). Two multinucleate strains were significantly more virulent on roots of leafy spurge than the other strains. Eleven cultivated plant species were found to be susceptible to at least one of the eight Rhizoctonia strains, having mean disease ratings significantly different (P=0.05) from those of control plants. Two or more strains caused significantly different mean disease ratings in eight of these host species, indicating that there was variation among strains
