The effects of Rhizoctonia solani on the hypocotyls of resistant and susceptible lines of lima bean were studied. The fungus attacks lima bean at one or more stages during host development and causes pre-and -postemergence damping-off, root rot, and foliage blight. The isolate of the fungus used in this study was obtained from infected radishes grown in Salt Lake County, Utah.

The formation of infection cushions and modes of penetration by this fungus was no different on the resistant and susceptible lima bean hypocotyls. The infection process was studied under laboratory conditions. Differential staining showed that the fungal hyphae were …
