SUMMARY Low soil moisture content during the critical period for infection by Streptomyces was obtained by covering plants after emergence with polythene tunnels. These were removed approximately 9 wk later. At lifting, tubers of susceptible clones were severely and evenly affected. Low soil moisture levels led to a relatively higher increase in the infection of King Edward tubers than of those of other cultivars. This interaction of cultivar with environment can account for discrepancies in reports of the performance of this cultivar.
