The standard injection method of inoculation was used in conjunction with the riddle‐abrasion method, at three periods during the storage season, to determine the effect of storage of potatoes of three varieties at three temperatures or ranges of temperature upon their subsequent susceptibility to Fusarium caeruleum. Susceptibility was greatly increased by increase in storage temperature. Low‐temperature storage (39°F.) before inoculation decreased susceptibility. If, however, such storage immediately followed inoculation, although little or no signs of rotting were obvious after 6 weeks, when these tubers were replaced for a further 6 weeks at the normal temperature of incubation (60°F.) the amount of rotting was enhanced. Some practical consequences of these facts are discussed.
