Abstract

Arthrobotrys conoides Drechsler,Arthrobotrys oligospora Fressenius andMonacrosporium rutgeriensis R. C. Cooke, Pramer belong to the peculiar group of predactious fungi which trap and kill nematodes. We have found that these cultures produce nematode-attracting and nematicidal substances the production of which is potentiated in the presence of nematodes. Our method of nematode attraction assay is also described.
