Effects of mycophagous soil mesofauna on Rhizoctonia solani infection
of potato stems were investigated in two experiments carried out in gr
owth chambers at 10 and 15 degrees C. The springtail Folsomia fimetari
a and the nematode Aphelenchus avenae were selected as organisms suppr
essive to R. solani. Reduction in Rhizoctonia stem infection by mycoph
agous soil mesofauna was equally effective at 10 and 15 degrees C. F.
fimetaria tended to be more effective than A. avenae, but the best con
trol was obtained when both organisms were present in the soil at high
densities.
