Mycoflora of various parts of the root systems of maize plants at the seedling and silking stages of growth were determined at 10 locations in Mississippi. Fungi isolated most frequently were Trichoderma spp. (from 39% of tissue pieces assayed). Fusarium moniliforme (21%), and F. oxysporum (13%) at the seedling stage and F. oxysporum (10%) at the silking stage. Frequency of specific fungi and total mycoflora varied considerably among the locations. Invasion was not associated with a particular part of the root system and was commonly associated with symptomless tissues.
