Abstract:	Fungi were isolated from the rhizosphere and rhizoplane of healthy or mildly diseased plants collected in areas of fields severely affected by sudden death syndrome of soybean (SDS), caused by Fusarium solani. Of the 151 candidate fungi evaluated for control of this disease in greenhouse tests, 46 demonstrated control activity. None of these isolates had in vitro antibiosis activity at either high or low nutrient levels. Seventeen of the isolates demonstrated significant control activity in two further tests. The predominate fungi demonstrating biological control activity were F. solani and F. oxysporum. Field tests of selected isolates did not result in significant levels of control but yields with one isolate were significantly greater than the control in 1992.
