Abstract
Sixty-five Rhizoctonia-like fungal isolates were obtained from plants exhibiting symptons of root disease from a forest nursery (Pinus and Quercus) in Spain or form samples sent to the laboratory of plant health (DARP, Generalitat de Catalunya). Three morphocultural groups were obtained: two groups (85%) were binucleate Rhizoctonia and the other (15%) were multinucleate and belonged to R. solani AG-5. The binucleates did not anastomose with the known AG isolates tested. RFLP-based dendrogram grouped binucleate isolates separately from multinucleate. Pathogenicity tests showed the multinucleate isolates were more aggressive than the binucleates against germinating seeds of Monterey pine.
