Resumen
A preliminary survey of fungi associated with the cyst-nematode Heterodera glycines Ichinohe in an Alabama soybean soil indicates the presence of several specific fungal pathogens as well as a population of miscellaneous incidental species that are at most only weakly parasitic. Fusarium oxysporum Schlecht., F. solani (Mart.) Sacc., and Exophiala pisciphila McGinnis and Ajello are implicated as major pathogens while Neocosmospora vasinfecta Smith, Phoma multirostrata (Mathur, Menon and Thirum.) Dorenb. and Boerema and Verticillium leptobactrum W. Gams are considered to be possibly involved in degradation of cyst cuticle.
