Techniques for Isolation and Evaluation of Fungal Parasites of Heterodera glycines

D. G. Kim, R. D. Riggs

Abstract


A facultative fungal parasite, Arkansas Fungus 18 (ARF18), was isolated from at least 10 different sources of Heterodera glycines in different areas in the United States. Techniques used for isolation and in vitro evaluation of fungal parasites of H. glycines were described. Successful isolation of probable egg parasites depends on isolation from individual eggs. Selective isolation and a simple, yet definitive, screening system can increase the possibility of identifying effective biocontrol agents. Key words: ARF18, biocontrol, egg parasite, Heterodera glycines, isolation, soybean cyst nematode, nematode suppressive soil, technique.
