Conteúdo: 	Two selective media using rice agar as the basal medium, were developed for the isolation and enumeration of Macrophomina phaseoli from soiland soybean plant debris. The first, designated as CC, was developed in India and contained chloroneb, methoxyethylmercury chloride (CeresanWt), streptomycin sulfate, and potassium penicillin. The second, designated as CMR, was developed at the University of Illinois and contained the same ingredients, except that mercuric chloride was substited for methoxyethylmercury chloride and rose bengal was added. Recovery of M. phaseoli from artificially infested soil was close to 100% with eihter medium. Assays with CC showed M.phaseoli persists in soil under diverse environmental conditions and that populations of the fungus insoil, increased with increased years of continuous soybean cropping. Populations of M.phaseoli in soil from Illinois soybean and corn fields, determined with CMR, were higher than those determined using the sclerotial-flotation method. In the absence of a suitable host, M.phaseoli population increased and mycellial inoculum persisted in soil up 7 days. The test fungus was capable of invading dead stem tissues in soilcontaining antagonistic microorganisms. the evidence does not support the strict classification of M.phaseoli as a root-inhabiting fungus.
