Rhizoctonia solani is another soil-borne pathogen that can infect both corn and soybeans. R. solani causes a brick red lesion to form on the roots and hypocotyls. Previously, Rival fungicide (a combination of PCNB, TBZ and Captan) was very effective as a seed treatment for Rhizoctonia solani, but it is no longer available.  There are several products currently labeled:  fludioxonil, ipconazole, carboxin + PCNB and strobilurin compounds.  There is limited data from Ohio on these compounds as the tests are quite severe and in greenhouse studies none of the fungicides provide complete control.  Rhizoctonia can infect throughout the season, thus combinations of host resistance and seed treatment are needed where this pathogen is a consistent problem.
