SUMMARY This paper describes a study designed to find a reliable sampling procedure for estimating the population of Verticillium duhliue in field plots that would not be too demanding in terms of the time required to assay soil samples. In the soil under study, the amount of time needed to obtain reliable estimates of the inoculum density was reduced by taking the larger plot sizes in the range considered, generally taking more plots with fewer samples per plot, and mixing the samples within a plot before redividing for assaying.
