Yarwood’s traditional and qualitative detection test for the soil borne pathogenic fungi Chalara elegans (synanamorph: Thielaviopsis basicola) and C. thielavioides (synanamorph: Chalaropsis thielavioides) in soils and substrates was modified in order to allow quantitative assessments of the population density of the fungi in soils. Preliminary results of independently repeated tests of different soils show a good repeatability in time with acceptable dispersion values for soil biology investigation methods. The validation of the new method is continued.
