SUMMARY Laboratory and pot experiments by various workers up to 1956 suggested that the effects of eelworm attack on certain crops could be partly overcome by inoculating eelworm‐infested soil with the mycelium of predacious fungi. The present paper demonstrates some of the factors operative in soil which affect the ‘predacity’ of some of these fungi. The results obtained strongly suggest that under laboratory conditions and in pot cultures congenial conditions for growth in soil of the predacious fungi can be produced but that, in the field, only sparse growth of these fungi can be obtained, insufficient to affect eelworm attacks. The use of farmyard or green manure has consistently given better crops in eelworm‐infested soils irrespective of whether predacious fungi were naturally present 01 added.
