TLDR
Experiments using nematode-free soil suggest that the presence of nematodes is necessary to initiate the formation of trapping organs, but that the fungi are incapable of remaining in a predaciously active state in the absence of an organic energy source other than the nem atodes.Abstract:
SUMMARY
The decomposition of sucrose in non-sterile soil stimulates an increase in both the population of free-living nematodes and the activity of indigenous nematode-trapping fungi. After sucrose decomposition reaches a certain stage the fungi cease to trap the nematodes still present in the soil. Increasing the amount of sucrose added to the soil stimulates greater increases in nematode population but results in a decrease in predacious activity of the fungi. Experiments using nematode-free soil suggest that the presence of nematodes is necessary to initiate the formation of trapping organs, but that the fungi are incapable of remaining in a predaciously active state in the absence of an organic energy source other than the nematodes. The significance of this is discussed.read more

Rhizosphere interactions and the exploitation of microbial agents for the biological control of plant-parasitic nematodes.
TL;DR: As nematodes influence the quantity and quality of root exudates, they are likely to affect the physiology of those microorganisms in the rhizosphere; such changes may be used as signals for nematode antagonists and parasites.

Fungi as Biological Control Agents of Plant-Parasitic Nematodes
TL;DR: In this chapter important nematode parasitic and antagonistic fungi are divided into nematophagous and endophytic fungi, and their taxonomy, distribution, ecology, biology and their mode of action are discussed.

Nematode-Trapping Fungi
TL;DR: Nematode-trapping fungi serve as an excellent model system for understanding fungal evolution and interaction between fungi and nematodes.

The soil-plate method for isolation of fungi from soil.
TL;DR: Yeast extract agar, acidified with phosphoric acid to pH 4.0, has been found a satisfactory medium for the growth and sporulation of many soil fungi and has been extensively used as an isolation medium.

Notes on the technique of handling predacious fungi
TL;DR: Methods used in the study of predacious fungi include techniques for obtaining mixed cultures of the fungi from Nature, for isolating those that will grow in pure culture, for observing living material and for making permanent microscopical preparations.

Nematode-destroying fungi in agricultural soils.
TL;DR: The results set out below are those of a survey carried out on forty-nine samples of soil from various parts of England, taken from arable land and from glass-houses in Warwickshire in which tomatoes were the principal crop, and in many of which the potato root eelworm was causing damage.
