Abstract
Crump, D. H., Sayre, R. M., and Young, L. D. 1983. Occurrence of nematophagous fungi in cyst nematode populations. Plant Disease 67:63-64. Females of the soybean cyst nematode and soil samples collected from several soybean-growing areas of Tennessee in July 1981 were examined for fungal pathogens with potential as biological control agents of the nematode. Females infected with Nematophthora gynophila were isolated at three sites from five samples of roots, and resting spores of the fungus were found at five sites in nine soil samples, including two sites where the nematode is declining. Females infected with Catenaria auxiliaris and resting spores of Verticilliwn chlamydosporium were also found. These fungi control populations of cereal cyst nematode in England.
