Parasitism and Lysis by Soil Fungi of Sclerotinia sclerotiorum (Lib.) de Bary, a Phytopathogenic Fungus

CONCERN about the widespread use of chemicals to control plant pathogens has made it desirable that alternative methods, including biological control1, should be examined. This study of natural fungal parasites of a plant pathogenic fungus indicates the potential of such organisms in controlling plant diseases.
