Abstract

One hundred and twenty-nine isolates of Rhizoctonia spp. were obtained from soil samples in Israel and from culture collections in the U.S.A. and Japan. The isolates varied in host range and disease severity when tested on six to eleven different host plants. Approximately 30% of the isolates were nonpathogenic to all the host plants tested. Mycelial growth rate of the nonpathogenic strains did not differ significantly from that of the virulent isolates. The 107 Israeli isolates represented anastomosis groups (AG) 1, 2, 3, 4, 5 and 6 of R, solani, two groups of R. zeae, and three groups of binucleate Rhizoctonia AG: A, F and K.
