SUMMARY In 1974 a severe outbreak of grey bulb rot ( Rhizoctonia tuliparum Whetzel & Arthur) occurred on tulips in Lincolnshire in a field not planted with a highly susceptible crop for six years. A long‐term experiment on the survival of R. tuliparum showed that about 10 per cent of sclerotia can remain viable for at least 10 years. Where severe outbreaks of disease have occurred, longer intervals between susceptible crops are suggested.
