Summary Carrots of variety ‘Nantes’were stored in air containing spores of Rhizopus stolonifer Lind. at a range of temperatures, humidities and air flow rates; temperatures from 2 to 30°C, relative humidities from 35 to 90%, and air flow rates from 20 cm sec ‐1 to 500 cm sec ‐1 . The rates of loss of weight from carrots stored under these conditions and the conditions under which invasion by R. stolonifer would occur were investigated. It was found that, irrespective of the storage conditions, predisposition of the carrot by the loss of at least 8% of its fresh weight was necessary before invasion would occur. Above this critical weight loss, the percentage of carrots invaded by the mould increased rapidly with increasing weight loss. An empirical method for predicting the rate of weight loss from stored carrots was devised.
