| Abstract: | Cultures of 99 strains fungi in potato-sucrose-malt extract medium were screened fornematicidal activity. Strong activity was found in the supernatant of the culture of fungusNo. 18 (Syncephalastrum racemosum (cohn) Schroter). Nematicidal activity-guided pre-liminary fractionation of the supernatant showed that the active substance was neutral andwater soluble. |
