Interaction Between Two Root Pathogens and the Epidemiology of Pyrenochaeta Glycines on Soybeans

The interaction between Fusarium oxysporum and Rhizoctonia solani in causing a root rot of soybeans was studied in the growth chamber and field. Disease incidence and severity tended to be higher and dry weights lower for plants inoculated with F. oxysporum + R. solani in comparison to either F. oxysporum or R. solani alone and the controls. In addition, competition and/or antagonism was apparent because R. solani inocula and root infection were lower in the presence of F. oxysporum than with R. solani alone. An interaction exists between F. oxysporum and R. solani.
